Topic: Conditional Sentence,

Best Answer Explained in Below-:

The sentence "If he has time, he – us next Friday." sets up a conditional statement about a possible future event. In English grammar, when using the present simple tense in the conditional clause (in this case, "If he has time"), the main clause typically follows a similar structure, often using the present simple or will-future form.

Option A, "visits," is the present simple form of the verb "to visit." It aligns perfectly with the structure of the sentence, indicating that if the condition of him having time is met, the action of visiting will occur. Thus, the sentence correctly reads: "If he has time, he visits us next Friday."

In contrast, the other options do not fit this structure:

- B) "would go" implies a hypothetical situation but does not match the simple future expectation set by the condition.
- C) "have gone" is past perfect and does not relate to the future context.
- D) "was gone" uses past tense, which is also not aligned with the forward-looking context of the sentence.

Therefore, "visits" is the only option that cohesively maintains the conditional nature of the statement and establishes a clear and plausible future action.
