Sajni had/interfere in/this matter.

Correct option is A

In English grammar, verb tenses must align correctly with the structure of the sentence. In the sentence provided, "Sajni had/interfere in/this matter," there is an issue with verb tense consistency.
• The verb structure "had interfered" represents the past perfect tense. The past perfect is used to express an action that was completed before another action or point in the past. It is formed using the auxiliary verb "had" followed by the past participle of the main verb.
• The verb "interfere" in the original sentence is in its base form, which is incorrect in this context because it doesn't agree with the auxiliary verb "had." To correct the sentence, "interfere" should be in its past participle form, which is "interfered." Thus, the correct phrase should be "Sajni had interfered in this matter."

​Grammatical rule used: In the past perfect tense, the structure is usually "Subject + had + Past Participle." Here, "interfere" should be in its past participle form, which is "interfered."​
