Question

When he ____ finished the exam, he'll speak to you. has is will will have

Answer 1

When he will have finished the exam, he'll speak to you.

• The verbs in a sentence are the action words that describe what the subject is doing. Verbs, which describe what is happening, are the primary component of a sentence or phrase together with nouns. In fact, even the simplest sentences—like Maria's song—have a verb because complete thoughts cannot be adequately expressed without one. Actually, a verb can be used to begin a sentence on its own by implying the subject, which is usually you in examples like "Sing!" and "Drive!"
• Almost always, verbs follow a noun or pronoun. The term "subject" refers to certain nouns and pronouns.

Here, the sentence is given as,

When he ____ finished the exam, he'll speak to you.

Here, the correct form of the verb will be,

When he _will have finished the exam, he'll speak to you.

Hence, the correct sentence is, when he _will have finished the exam, he'll speak to you.
