Answer 1

Hint: A complete sentence must have, at minimum, three things: a subject, verb, and an object. The subject is basically a noun or a pronoun. And, if there's a subject, there are required to be a verb because all verbs need a subject.

Complete answer:
A verb is a term that conveys an event, an occurrence, or a state of being in syntax. It comes from the Latin verbum, which means "word" (be, exist, and stand). The infinitive is the simplest form of English, and it can be used with or without the particle to. The present tense indicates that an action is being carried out; the past tense indicates that an action has been completed; and the future tense indicates that an action will be carried out.

The simple future is a verb tense that’s used to discuss things that haven’t happened yet, here, phoning Ruth. We use the simple future to talk about an action or condition that will initiate and end in the future. The formula for the simple future is will + [root form of verb], that is, will phone, or, I'll phone. Hence, Option A is correct.

The rest of the options do not obey this condition. Options B and C state actions that have already happened, and D states an action that has been occurring in the future. Option D does not have a clear meaning. Hence these options are incorrect.

Hence the correct is option ‘A’.

Note:
Difference between verb and tense - The verb is (grammar) a word that shows an action, event, or state while tense is (grammar) any of the types of a verb which differ when an action or state of being occurs or exists.

Verbs come in three tenses: past, present, and future. The present tense is used to explain things that are happening right away, or things that are continuous. The future tense describes things that have still to happen (e.g., later, tomorrow, next week, next year, three years from now).
