Which policy would be in the best interests of consumers?

A:increasing tariffs
B:decreasing minimum wage
C:breaking up large companies to increase competition
D:changing loan interest rates to encourage saving rather than borrowing

C: breaking up large companies to increase competition.

Increasing tariffs would likely lead to higher prices for consumers, as it would make imported goods more expensive.

Decreasing minimum wage could potentially harm consumers, as it could result in lower wages for workers and potentially lower purchasing power.

Changing loan interest rates to encourage saving rather than borrowing could have mixed effects on consumers, as it would depend on individual financial situations and needs.

On the other hand, breaking up large companies to increase competition can benefit consumers by promoting lower prices, better quality products, and more choices in the market.
