What type of pronoun is used in the following sentence WHICH beach are we going to demonstrative interrogative indefinite relative?

The pronoun used in the sentence "WHICH beach are we going to?" is a relative pronoun.

Here's why:

* Relative pronouns connect a dependent clause to an independent clause. They introduce a clause that provides more information about a noun in the main clause.

* In this sentence, "WHICH beach" refers to a specific beach, making it the antecedent. The dependent clause "WHICH beach are we going to" provides additional information about the beach.

Let's break it down:

* Independent clause: "We are going to the beach."

* Dependent clause: "WHICH beach"

The relative pronoun "WHICH" connects these clauses and acts as the subject of the dependent clause.
