Allowing one vocal member who feels strongly about an issue to make choices for the entire group is most characteristic of:

A) Averaging of individual opinions
B) Consensus
C) Persuasion by a recognized expert
D) Rule by an individual

This scenario is most characteristic of "Rule by an individual," where one person, in this case, a vocal member who feels strongly about an issue, makes decisions on behalf of the entire group. This contrasts with consensus (where the group collectively agrees), averaging of opinions (where the group's decision is an average of individual opinions), or persuasion by a recognized expert (where decisions are influenced by the expert's advice).
