When Simon . . . . . . . . back tonight, he’ll cook dinner. A. comes B. will come C. come D. shall come

The correct answer is: B. will come

The sentence is in the future tense, so we need to use a verb that is also in the future tense. The verb “comes” is in the present tense, so it is not the correct answer. The verb “come” is in the infinitive form, which is not used in this type of sentence. The verb “shall come” is an archaic form of the verb “will come,” and it is not commonly used in modern English.

Here is a more detailed explanation of each option:

• A. comes is in the present tense. This is not the correct answer because the sentence is about something that will happen in the future.
• B. will come is in the future tense. This is the correct answer because it is the only option that is in the future tense.
• C. come is in the infinitive form. This is not the correct answer because the infinitive form is not used in this type of sentence.
• D. shall come is an archaic form of the verb “will come.” This is not the correct answer because it is not commonly used in modern English.
