Identify the underlined part of the following sentence: Esperanza's mother says that she will never marry Luis.​

Dependent clause

Explanation:

It cannot be either a prepositional phrase or dependent phrase because phrases do not contain a subject and a verb ( which the underlined part contains)

It is not an independent clause because it does not make a complete meaningful sentence on its own.

It is therefore a dependent clause. A dependent clause has a subject and verb, is introduced by a subordinate conjunction/relative pronoun but does not express a complete thought.

the correct answer would be d.
