Fill in the blank with the correct form of the verb with the help of the hint given in the bracket:

(completed action by a certain time in the future)

By next month, he ______(sell) all his books.

• A. sell
• B. selling
• C. will sell
• D. will have sold

Answer 1

The correct option is D will have sold

A verb is used to express an occurrence, action, or state. It is the grammatical centre of the predicate in a sentence. Option D)will have sold is correct as the future perfect tense is used to indicate an action that will be finished between now and sometime in the future. The other options are wrong as no other tense can be used here. The correct answer is D)will have sold.
