When an economy operates near full capacity, additional money in circulation leads to inflation, as demand exceeds the economy’s ability to increase supply.

B is correct because inflation is the primary impact when supply cannot keep up with excess demand.

A is incorrect because output does not significantly increase when capacity is already maximized.

C is incorrect because velocity measures the rate at which money circulates, not the impact of oversupply.

D is incorrect as unemployment is already low when the economy is at full capacity.
