Question

adam smith believed that fair prices for goods are determined in a capitalist system
through competition between businesses.
by government regulation of businesses
by setting limits on imports and exports.
through competition between consumers.

Explanation:

Adam Smith, a foundational thinker in classical economics, argued that in a capitalist system, the "invisible hand" of competition between businesses (seeking profits) drives fair pricing: businesses will adjust prices to attract customers while competing with rivals, leading to equilibrium fair prices. He opposed government interference in pricing, and consumer competition or trade limits are not his core argument for fair pricing.

Answer:

through competition between businesses.
