Problem

The car whom I bought last year has been very reliable; I’ve driven it across the country without any mechanical issues or significant problems so far.

Clue

Relative pronouns connect a clause to describe a noun — choose based on whether it’s a person, thing, or place.

Hint

Use “who/whom” for people, “that/which” for things, and “where” for places.

Choices

5

Choice-A

Choice A is incorrect. “Whom” is only used for people as the object of a verb or preposition. Since “car” is a thing, this usage is incorrect.

Wrong No change

6

Choice-B

Choice B is incorrect. A relative pronoun, "which" refers to things and introduces nonrestrictive clauses—extra information set off by commas. In contrast, restrictive clauses (no commas) identify or define the noun, and in such cases, that is preferred; therefore, "which" is not used here because the clause “which I bought last year” is essential to identify the car, not just add extra detail.

Wrong which

7

Choice-C

Choice C is incorrect. “Where” is a relative pronoun for places or locations, not for objects or things.

Wrong where

8

Choice-D

Choice D is correct. “That” correctly introduces a defining clause for things or objects. It specifies which car was bought.

Correct that
