All of the following are individuals who may function as a center of influence EXCEPT:

A) salespeople who are selling competing products.
B) officers of community organizations like the chamber of commerce.
C) members of organizations such as the Lions Club.
D) country club members.
E) clergy.

Centers of influence are individuals who can influence opinions or actions of others, typically due to their position, expertise, or social standing. Salespeople selling competing products are generally not considered centers of influence in this context because their primary interest is in promoting their own products, not in serving as a neutral or positive influence within a community or organization.
