Q. Which one of the following is necessary for Pressure Groups to be effective in influencing Government Policy?

The correct answer is (C) Money and Expertise.

Explanation:
Pressure groups aim to influence government policies and decisions. To be effective, they require resources such as money to fund campaigns, organize events, and lobby policymakers. Additionally, expertise is crucial to present well-researched arguments, draft policy proposals, and provide credible information to decision-makers. While access to media outlets, legal support, or a large membership base can be helpful, they are not as critical as financial resources and specialized knowledge in ensuring the group’s influence.
