Best Answer Explained in Below-:

In the sentence "You keep (to interrupt) while I am talking," the phrase "keep (to interrupt)" needs to be evaluated for grammatical correctness and suitability. The verb "keep" is often followed by a gerund (verb+ing form) to indicate ongoing action. In this context, we're describing a continuous behavior that occurs while the speaker is talking.

The correct form is "interrupting" because it maintains the gerund structure needed after the verb "keep." This results in the correct phrasing: "You keep interrupting while I am talking." Using "to interrupt" (option A) would imply an infinitive, which is incompatible with "keep" in this context. The other options, "interrupt" (B) and "interrupted" (C), do not fit grammatically either; "interrupt" is a base form that lacks the necessary gerund form, while "interrupted" suggests a past action rather than an ongoing one.

Therefore, "interrupting" fits perfectly, emphasizing that the interruption is a repetitive and continuous action occurring during the speaker's dialogue. This choice captures the intended meaning and maintains proper grammatical structure.
