The concept of the relativity of deviance is best illustrated by which of the following statements?
a) it is not the act itself, but the reaction of others to the act that makes it deviant.
b) the nature of one's behavior is the most important aspect in determining deviance.
c) deviance is most related to functionalism because it creates a dysfunction for society.
d) deviance is analogous to mental illness.

The answer is:  A. it is not the act itself but the reaction of others to the act that make it deviant

A certain act would only be considered as 'deviant' if that act is violate the moral standard that is held by the majority of people in society

for example, in united states having sex before marriage would not be considered as a deviant behavior because it is generally common for couples in this country to do it. But,  this exact same cat would be considered as a deviant in countries with Muslim majority because it violate the rules in their religion.
