Identify the portion that contains a compound subject.

During the 1940s and 1950s, Budd Abbott and Lou Coastelle were a popular comedy team on radio, television, and stage.

A. 1940s and 1950s

B. Budd Abbott and Lou Coastelle

C. radio, television, and stage

D. none

I believe the correct answer from the choices listed above is option B. The compound subject in the sentence above would be Budd Abbott and Lou Coastelle. When a sentence has two or more subjects, that's called a "compound subject." Hope this answers the question.
