Concept:
Identifying the core theoretical frameworks associated with the founders and major contributors to sociological theory.
Step 1:
Emile Durkheim is a foundational figure in "Functionalism" (III), as his work focuses on how social institutions and structures maintain social solidarity and order.
Step 2:
Karl Marx's work centers on class struggle and the critique of capitalism, which provides the foundational basis for the "Conflict perspective" (I) in sociology.
Step 3:
August Comte is credited with naming the field of sociology and proposed "Positivism" (IV) as the methodology of using scientific observation to study society.
Step 4:
George Herbert Mead was a pioneer in "Interactionism" (II), specifically Symbolic Interactionism, focusing on how individuals construct meaning through social interaction.
Step 5:
By matching these thinkers to their theories (A-III, B-I, C-IV, D-II), we confirm that option (3) is the correct answer.
$$\boxed{\text{(3) A-III, B-I, C-IV, D-II}}$$
