I took the test the answer is C.
Answer:
B
Explanation:
Using a Z pattern is an example of a tactic that can be very effective in keeping the audience involved in the speech. Focusing too much on any one person can make that uncomfortable and also distract the speaker.
Scanning the room in a Z type pattern gives every member of the audience the illusion of being looked at and addressed individually by the speaker. This is useful tactic because people who feel involved will pay more attention to the subject matter.

(Buses being armored like tanks)
