b) could
c) can

Answer 1

Answer:

could have is the answer.......

Answer 2

This blank can be filled with the word 'could'.

So, option (b) is correct and correct sentence will be:-

If I were a boy, I could understand.

Could is past form of can. This is used in past tense or perfect tense.

We can detect whether the sentence is in present, past or future by looking the sentence structure.

Here, were is used so sentence is in past tense.

Hence, past form of helping verb will be used that is could.
