Question

choose the grammatically correct sentence. the girl and his friends exercise every day. the girl or his friends exercise every day. the girl and her friends exercise every day. the girls or her friends exercises every day.

Explanation:

• For the first option: "The girl" is female, so "his" (used for male) is incorrect.
• For the second option: "The girl" is female, "his" is incorrect, and also the subject - verb agreement with "or" (the verb should agree with the nearer subject "friends", but the pronoun is wrong).
• For the third option: "The girl" (female) uses "her" correctly, and the subject "The girl and her friends" is plural, so the verb "exercise" is correct.
• For the fourth option: With "or", the verb should agree with the nearer subject "friends" (plural), so "exercises" (singular) is incorrect, and also the pronoun "her" with "the girls" (plural) is a bit odd, but the main error is subject - verb agreement.

Answer:

C. The girl and her friends exercise every day. (Note: Here we assume the options are labeled as A, B, C, D with A being the first option, B the second, C the third, D the fourth. So the correct option is C. The girl and her friends exercise every day.)
