Nodding is a form of non verbal communication where one seems to agree or disagree with what the speaker is talking about ....it means either yes or No
A nod of the head is a gesture in which the head is tilted in alternating up and down arcs along the sagittal plane. In many cultures, it is most commonly, but not universally, used to indicate agreement, acceptance, or acknowledgement.
Explanation:
The human head-nod is a vertical, up-and-down (or down-and-up) movement that is often used to show agreement or comprehension while listening. The flexed-forward, lowering motion of the skull is also used to emphasize an idea, an assertion, or a key speaking point.
Explanation: Cause and Effects Citations are when one is to look for a solution to a problem, most often, and D (last option) is the only option that does so and spells it out.
