A. Trustee-deputy role

B. Facilitator-neutral role

C. District state or country role

D. Revolutionary role

Choose the most appropriate answer from the options given below: 

In his book "The Legislative System: Explorations in Legislative Behavior" published in 1962, John C. Wahlke introduced three distinct typologies for understanding legislative behavior. These typologies provide a framework for categorizing and analyzing how legislators approach their roles and interact with various stakeholders. These are:

• The trustee, politico, delegate typology.
• The facilitator, neutral, register typology 
• The state-oriented, district-state-oriented, district-oriented typology.

In addition to these typologies, Wahlke also employed a Likert-type scale to measure legislators' friendliness toward pressure groups and to explain how legislators interact with external actors in the legislative process. These roles are: 

• Trustee-delegate role  

• Facilitator-neutral role 

• District, state or country role 

​Therefore, the correct answer is A, i.e. A, B, and C.
