'The phone is ringing. Who do you think it is?' 'It ___ be Tim.' (Uncertainty)

• A. can
• B. could
• C. may
• D. will

Answer 1

Answer: (B), (C)

The correct options are
B may
C could

Modal Verbs show us the attitude of the speaker to what is being said or done. The term "modal" means expressing mood and mood is a way to express the attitude of the speaker

Option B is correct because it expresses uncertain ability.

Option C is also correct because it expresses uncertain possibility. Therefore both the answers express uncertainty.

Whereas option A expresses certain ability and option D expresses certainty in performance in future.
