Concept:
Talcott Parsons developed the "pattern variables" to represent the five binary dilemmas that actors face when making decisions in social systems.
Step 1:
The five variables are: Affectivity/Affective Neutrality, Self-orientation/Collectivity-orientation, Universalism/Particularism, Ascription/Achievement, and Specificity/Diffuseness.
Step 2:
"Affectivity vs Affective neutrality" (A), "Specificity vs Diffusion" (D), and "Collective vs self orientation" (E) align exactly with these established theoretical categories.
Step 3:
"Structural vs formal constraints" (B) and "Organisation vs Institutional structure" (C) do not appear in Parsons' list of binary dilemmas for social action.
Step 4:
The identified components—A, D, and E—correctly categorize the choices an actor must make according to the Parsonian system.
Step 5:
Because A, D, and E are valid pattern variables, option (2) is the correct choice.
$$\boxed{\text{(2) A, D, E Only}}$$
