Confusion about organic theory
 

Organic theory of society was first proposed by Spencer. Later on, durkheim and robert merner both associated society with a human body. I just need to know if organic theory question is asked, do we have to mention all these sociologists' view about organic society or merely stick with Spencer's theory?

Well that depends on the question. If it asks with reference to some specific theorist then describe that person's theory, or else give a general overview of all the major ones that are related to the theory.
