I choose C, which points out that comparing irradiation and cooking is misleading.
I do not pick A because it does not make the argument misleading. Even if the proponents are gaining from irradiation, their argument can still hold, as long as it is valid. Just like I am selling BMW and I claim that BMW is better than Audi in quality. Even though I could profit from my argument, if my point is valid, it is not misleading.
I do not pick E because I do not see how E makes the conclusion misleading. If the conclusion is that cooking irradiated food will only lose double the amount of VB1, E is right. The conclusion here is that irradiation is no worse than cooking. E could not counter either the argument or the conclusion.
I do not have the final answer. Personal opinion open to argument.

The author of the passage contends that “(irradiation) lowers the nutritional value”. Proponents of irradiation point out that irradiation is no worse in this respect [the respect of lowering the nutritional value] than cooking. In arguing for their position, the proponents cite one fact (irradiation is no worse than cooking – when compared separately), and “conveniently” omits another fact (irradiation and cooking used together cause double nutritional loss). So, the mentioning of only the first fact is misleading.
C points out that irradiation and cooking are at different stage of food processing and serve different purpose, but the difference alone does not weaken much the proponent’s argument, thus, it does not potently point out how the proponents’ argument is misleading.
Open to discussion.

偶也選E來著,不解中..
說說我的想法:其實C和E思路基本相同,只差往前走一步
beside the point:需要生吃的時候根本不需radiation---VB1本來就不應損失,所以beside the point
misleading:需要煮熟的時候, 大家會被誤導認為radiation損失小,但是實際上VB1損失不能只考慮radiation,還要加上cooking (V loss during radiation<storage of food> + V loss during cooking<preparation of food for consumption>)

I stick to C. Since the argument is about "irradiation is no worse than cooking", C points out that these two are not comparable in the first place.
E is not relevant unless the argument is about something else, such sd "the VB that irradiation removes/destroys is exactly the amount that human being will not be able to absorb and therefore irradiation does not cause nutrition loss"
I was leaning towards E at first. E does look like a typical GMAT answer

設Irradiation 降低nutrition value 4, cooking 降低 nutrition value 5.
Proponents of irradition的 evidence是:in this respect(通過比較irradiation,和cooking) 結論:no worse than cooking
E:for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded.
對於any food that is both irradiated and cooked. the reduction of vitamin B1必然是4+5,可這並不能反駁Proponents of irradition的evidence.就不能指出misleading.我一直認為E是無關選項
而C:通過指出Proponents of irradition的evidence.中irradition 和cooking不具備可比性。就指出了misleading.

I firmly stick to E. The proponent of irridation states that cooking destroys Vb more than irridation does. The reasoning of the proponent is that cooking destroys Vb but cooking is OK , so irridation is OK.
C doesn't weaken this reasoning. E points out irridaion will double the damage on Vb of cooking, thus irridaion is not OK if cooking is a must-be. So, E points out that the proponents are misleading

偶也選E。
本文作者的觀點是食物輻射會降低許多食物的營養價值。
而支持食物輻射的人反駁:就降低維他命B1來講,輻射並不比煮食物更糟糕。
作者又說,這個實事是離題的:
因為很多食物並不需要煮來吃。(意思是一種情況根本不會發生,所以沒有可比性)。
作者繼續說,或者這個實事是誤導的:
c: 煮食物通常是食物吃之前的最后一步加工過程(暗含的意思是不可避免的一步),
而輻射只是為了更長的保存食物。(暗含的意思是可以省略的一步,那麼跟上面離題的說法是不是一樣?兩種情況並不是一定要發生的,所以沒有可比性。-跑題?)
e. 同時輻射和煮食物,使流失的B1加倍。(指出即使輻射並不比煮食物使B1流失更厲害,但是有了它會加重流失。簡化之,A不比B糟,不代表說A就應該使用。)
請NN指正。謝謝!

C.
C的意思是cooking是准备吃东西之前的一个通常的步骤, 而irraidiation只是为了把食物保存的时间长一些, 两者的目的和用途都不一样, 所以misleading.
