Select the option that will improve the highlighted part of the given sentence.
I know a person who parents live in Milan.

Correct option is B

The correct substitution of the highlighted words is "whose parents."
Explanation:
· "Whose" is a relative pronoun used to indicate possession.
· The sentence talks about the parents belonging to the person, so "whose" is the correct word.
· The structure should be:
· Subject + whose + noun + verb
Grammatical Rule Used:
· "Who" is used for subjects, but it cannot show possession.
· "Whose" is the correct possessive form.
Example:
· Incorrect: The girl who dress is red is my friend.
· Correct: The girl whose dress is red is my friend.
Incorrect Options:
· (a) "whom parents" – Incorrect because "whom" is used for objects, not possession.
· (c) "what parents" – Incorrect as "what" is used for unknown things.
· (d) "which parents" – Incorrect as "which" is used for selection, not possession.
