Select the most appropriate option to fill in the blank.
I saw a man _______ was wearing a black coat.
Show answer & explanation
Correct answer: C
Explanation
Who: It acts as the subject of the relative clause ("...was wearing a black coat") and refers to a person (the man).
Which: This is used to refer to objects or animals, not people.
Whom: This is used for people when they are the object of a verb or preposition (e.g., "The man whom I saw..."). In this case, the pronoun is the subject performing the action of wearing the coat.
Whose: This is a possessive pronoun (e.g., "The man whose coat was black..."). It does not fit the grammatical structure of this sentence.
Therefore, the most appropriate option to fill in the blank is ‘who’.
The complete sentence is: "I saw a man who was wearing a black coat."
