Identify the sentence that has correct subjectdash–verb agreement. a. when professor jones lectures, everybody listen and take notes. b. when professor jones lectures, everybody listens and takes notes. c. when professor jones lectures, everybody listens and take notes. d. when professor jones lectures, everybody listen and takes notes.

The correct option is B " When Professor Jones lectures, everybody listens and takes notes". Because there is agreement between the subject "everybody" and the verbs "listens" and "takes". the subject and the verbs are in singular form. In the rest of the examples, this rule is not applied and one or both verb is not in the singular form.
