The verb to be has how many forms in the present tense? A. one B. two C. three D. four

They are actually up to five forms for each verb:

root,

third-person singular,

present participle,

past,

past participle.

So I say four. I hope this is it!

I believe that the answer would one. So your answer would be option A.

Let's take an example: "Sarah is kicking the football."

"Sarah is (kicking) the football"

The word 'kicking' would be the only verb in this sentence. And we also see this is a present action. Therefore, option (a) would be the answer.
