I rode my bike, . . . . . . . . has a headlight, home in the dark. A. that B. whom C. which D. whose

The correct answer is: C. which

The sentence is about a bike that has a headlight. The bike is the subject of the sentence, and the headlight is a descriptive detail about the bike. The pronoun “which” is used to refer to non-human objects, so it is the correct pronoun to use in this sentence.

The other options are incorrect because they are not used to refer to non-human objects.

• A. that can be used to refer to both human and non-human objects, but it is more commonly used to refer to human objects. In this sentence, it would sound like the bike is a person.
• B. whom is used to refer to people, not objects.
• D. whose is used to refer to people or objects that possess something. In this sentence, the bike does not possess anything, so “whose” is not the correct pronoun to use.
