This is the hotel . . . . . I had stayed last night. A. which B. that C. where D. costly

which
that
where
costly

The correct answer is C. where.

The word “where” is used to introduce a place or location. In this sentence, the speaker is referring to a specific hotel where they stayed the previous night. The other options are incorrect because:

  • Which is used to introduce a choice or an option. In this sentence, the speaker is not making a choice between hotels.
  • That can be used to introduce a clause that provides additional information about a noun. In this sentence, the speaker is not providing additional information about a noun.
  • Costly is an adjective that describes something that is expensive. In this sentence, the speaker is not describing the hotel as expensive.
