The correct option is C Dialogues and negotiations
Pressure groups are organisations that
attempt to influence government
policies. But unlike political parties,
pressure groups do not aim to directly
control or share political power. These
organisations are formed when people
with common occupation, interest,
aspirations or opinions come together
in order to achieve a common objective. There is always some direct or indirect relationship of political parties and relation groups to reach a conclusion of particular demand made or interest raised for which dialogues and negotiations are the methods applied so as communication formally can take place.
