(A) It/him
(B) Its/his
(C) It/one
(D) the/his
🧠 Explanation:
- The sentence requires possessive pronouns to show ownership — the tail belongs to the lizard, and the hand belongs to the boy.
- “Its” is the correct possessive form of “it” (referring to the lizard), while “his” correctly refers to the boy’s hand.
- Option (A) “It/him” is incorrect because “it” is not possessive, and “him” is objective, not possessive.
- Therefore, the grammatically correct and meaningful sentence is: “When the little boy grabbed the lizard, its tail broke off in his hand.”
