Answer:
Talcott Parsons researched A. the sick role.
Explanation:
The sick role is a term in Sociology, refering to sickness and the rights and obligations a sick individual has.
Parsons was a functionalist sociologist, meaning that all parts of society are important for its long-term development. When someone is sick, he/she is no longer functional within the society and thus has to be taken care of since it comes with a "sanctioned deviance" role.
