Correct option is D
Option (d) contains an error.
The error lies in the incorrect use of the auxiliary verb “has” with the subject “I.” The correct helping verb with "I" is
"have". The
Present Perfect Continuous tense structure is:
Subject + has/have been + verb-ing
Since the subject is “I,” we must use “have been.”
Correct sentence: I have been visiting my family and relatives during the winter vacation.
Grammatical rule used:
➤ In the Present Perfect Continuous Tense, "has" is used with third-person singular (he, she, it) and "have" is used with all others (I, you, we, they).
Example:
· Incorrect: She have been working hard.
· Correct: She has been working hard.
Information Booster:
Using the correct form of “has” or “have” with different pronouns is essential for forming proper tenses.
