I’m filling up an application for off-campus housing that you were doing last week? Do you remember if you had included the name and phone number of the manager of the dorm that you live now?
I asked in the housing office and they told me it’s optional!
What does the woman imply?

A. Off-campus housing is too far away from the camps.
B. The man can include the name of the dorm manager if he wants to.
C. The man should ask someone else for the information.
D. The man should ask the dorm manager for a reference letter.

從哪裡得知答案要選B呢？？謝謝
