Answer:
A (Sorry, again!)
Step-by-step explanation:
This one is confusing, but I believe B,C, is wrong. I'm not sure, but those answers don't really make any sense expect for A, D. But, since the question said GDP. GDP can be calculated by adding up all of the money spent by consumers, businesses, and government in a given period. Which is talking about money and the marketing in government. So, it's A most likely. Sorry, if I didn't answer it fully.
