Concept:Political parties and pressure groups both connect citizens to government by expressing and combining interests.
Explanation:Interest aggregation means combining different demands into clear policy options.
Interest articulation means expressing the views and needs of the people to those in power.
Both political parties and pressure groups perform these two functions.
For example, a political party gathers many social and economic demands into a manifesto.
A pressure group also collects the concerns of its members and presents them to the government.
Therefore, option A correctly identifies a function common to both organisations.
Option D is wrong because only political parties seek to manage state affairs.
Option C is more specific to pressure groups, and option B is not a basic function of both.
Answer:A. interest aggregation and articulation
