The best answer choice from the options given to answer the question: What is the one defining feature of a minority group, would be, C: Lack of power.

Explanation:

A minority, be it racial, cultural, or ethnical, is a group of people with a defined common set of characteristics, that are small in number, and that usually coexist with a much larger group. For example, the Hispanics are a minority group, in America. One defining feature of a minority group is that because of their small numbers, they tend to be dependent on the will, and control, of the larger group, and they have very little effect on how the different aspects of life are carried out, because they cannot outweigh the power of the larger population.
