Assertion (A) states that bringing down the influence of the rich and powerful is a challenge in the concept of 'expansion of democracy'. This is incorrect. 'Expansion of democracy' typically refers to extending democratic rights, processes, and institutions to new areas or populations (e.g., universal suffrage, decentralization). Bringing down the influence of powerful elites is a challenge related to the quality or deepening of democracy. Reason (R) states that people's participation and control are meaningful only when the influence of the rich is brought down, and this results in "Deepening of Democracy". This statement is correct. Deepening democracy involves making democratic processes more responsive, inclusive, and participatory, reducing the undue influence of money and power to ensure more equal political voice.
