Choose the part of each sentence that is a dependent clause.

When their ship docked, the immigrants had numbered identity tags pinned to their clothing.

a. when their ship docked

b. immigrants had numbered identity tags

c. pinned to their clothing

A. when their ship docked

Explanation:

A dependent clause is a group of words with a subject and a verb. However, it cannot stand alone as it does not express a complete thought. B expresses a complete thought and can stand alone as a sentence, so we can eliminate that as a possible answer. Although C can seem like a possible answer, A is a better choice because it features the dependent marker "when".
