Which sentence from the passage contains a relative pronoun? A. I went with my cousin, whom we all like. B. Everybody was very tired near the end of the trip. C. Whose idea was that? D. This was my first choice for a vacation.

The correct answer is: I went with my cousin, whom we all like.

The relative pronoun here is whom.

A relative pronoun is used to connect a clause or a phrase to a noun or pronoun. The clause modifiers or describes the noun.

Whom refers to my cousin and describes him : whom we all like (we all like him). The clause describing the subject (my cousin) is called the relative clause. It is always introduced by a relative pronoun such as: who, whom, which, that.
