9) Go and find the driver arrived here yesterday A) he B) who C) whose D) what E) whom

The correct answer is B) who.

The sentence should be: "Go and find the driver who arrived here yesterday."

Explanation:

• "Who" is a relative pronoun used to introduce a clause that provides more information about a noun mentioned before. In this case, it provides more information about "the driver."
• "He," "whose," "what," and "whom" do not fit grammatically in this context.
