Answer:
B. Budd Abbott and Lou Costello
Explanation:
A compound subject is a subject consisting of two or more nouns, often joined by a comma or by coordinating conjunction like or, nor, and or neither. The portion of the sentence that contains a compound subject, then, is โBudd Abbott and Lou Costelloโ because it is what is being mainly described in the sentence and it consists of two names of people (that is, nouns) joined by the conjunction โand.โ
