Concept:A non-partisan organisation that influences government policies without seeking to control the government is a pressure group.
Explanation:Pressure groups are organised bodies that aim to shape or influence government policies.
They do not contest elections or aim to form the government, so they remain non-partisan.
They use methods like lobbying, protests, and public campaigns to pressurise decision-makers.
Political parties, on the other hand, seek political power through elections.
Humanitarian and relief organisations focus on aid and welfare, not direct policy influence.
Therefore, the correct option is B. Pressure group.
Answer:B. Pressure group
