b. will need
c. needs
d. need

Answer 1

I think the answer is b.
A and c definitely don’t make sense.
D kinda does but I think it’s improper.

Answer 2

Answer:

Either one is possible:

b. will need  

c. needs  

Explanation:

In the case of 'needs,' -- when using either-or constructions --  If one subject is singular and the other is plural, and the words are connected by the words "or," "nor," "neither/nor," "either/or," or "not only/but also," use the verb form of the subject that is nearest the verb.
