Write the verb "go" in the present perfect tense. Use the pronoun "I" as the subject.

A. I have gone.

B. I am going.

C. I go.

D. I am gone.

The answer is A. i have gone

In the present time it would be

I am going because you are saying that you are going now (present)

I have gone is that you went in the past.

I go is another present sentence.

I am gone doesn't make make any sense.

So the answer is I am going (A)
