The dependent clause in the sentence "This is the ship that drowned in the waters" is:
A. that drowned in the waters
Here's why:
1. A dependent clause is a group of words that contains a subject and a verb but does not express a complete thought and cannot stand alone as a sentence.
2. In this case, "that drowned in the waters" is the dependent clause because it starts with the relative pronoun "that" and describes the ship that drowned, but it cannot stand alone as a complete sentence.
So, the correct answer is option A: that drowned in the waters. This part of the sentence cannot stand alone and relies on the rest of the sentence to make sense.
