For the second question regarding the sociological perspective that would be most interested in examining the lobbying movement, the correct answer is:
Option C: Functionalism.
Functionalism would analyze how lobbying serves functions within the political system, including its role in maintaining stability and order in governance.
However, it's worth noting that both symbolic interactionism and exchange theory could also provide valuable insights into the dynamics of lobbying. But in terms of the most relevant perspective, functionalism is typically viewed as focusing on the broader social structures and their functions.
