Early study of public speaking was known as:

A. public communication.
B. rhetoric.
C. public relations.
D. communication study.

my guess is B.rhetoric

Right.

The correct answer is B. rhetoric.

Rhetoric is the early study of public speaking. To arrive at this answer, you can use a couple of techniques. The first is to rely on prior knowledge or recall if you have any information about the history of public speaking. If not, you can use a process of elimination by looking at the other options and recognizing that they do not specifically refer to the early study of public speaking. Another option is to use external resources such as textbooks or online articles that discuss the history of public speaking and its early study.
