Question

lower prices act as an incentive for consumers to:
buy more
stop purchasing
save all income
buy less

Explanation:

In economics (a subfield of Business), the law of demand states that, ceteris paribus, as the price of a good or service decreases, the quantity demanded by consumers increases. Lower prices make goods more affordable, so consumers are incentivized to buy more of the good. "Stop purchasing", "save all income", and "buy less" are inconsistent with the typical consumer response to lower prices.

Answer:

A. Buy more
