Answer:
The option which correctly identifies the subject and the verb of the sentence is:
d. The subject is "hammock" and the verb is "swayed."
Step-by-step explanation:
The subject of a sentence can be described as the sentence's topic, that is, what the sentence is about. The verb of a sentence often expresses the action performed by the subject or helps connect the subject to a description about it. In the sentence we are analyzing here, the subject is "hammock". What is there to know about this hammock? That it "swayed" in the breeze. "Swayed" is the action performed by the hammock and, therefore, the verb of the sentence.
