The sentence that best revises the subject-verb agreement error in the sentence is <span>B. The dogs or the cat is responsible for the mess. </span>The reason for this is because the verb agrees with the noun closest to it when it comes to using the conjunction <span>or.</span>
It is C. adjective. Large is describing the large anchor chain. The others would not work as well. A proper noun is a name for a person/place etc. An abstract noun expresses feelings or thoughts. Good luck!!
