A person who refuses to conform to societal norms may be considered ____________.

The term "nonconformist" refers to someone who chooses not to follow established customs or rules, often challenging societal expectations. It originates from "nonconformity," which describes the state of resisting accepted norms. In this context, a nonconformist stands out because they embrace individuality and might express alternative beliefs, behaviors, or lifestyles that differ from those commonly accepted.

The other options do not fit the definition of a person who refuses to conform. "Conform" is a verb that describes the action of aligning with standards; "conformist" refers to someone who does adhere to the norms and values of a society; while "nonconformity" is the noun form that describes the act of not conforming, but it does not describe the person engaging in that behavior. Therefore, "nonconformist" is the most appropriate choice for describing someone who actively rejects societal norms.
