What are four types of consumer-protection regulations?

Four types of consumer-protection regulations include truth-in-advertising laws, which require that advertisements be truthful and not misleading; product safety regulations, ensuring that products meet safety standards to protect consumers from harm; privacy laws, which protect consumers’ personal information from being misused; and warranty laws, which govern the guarantees and returns of products to ensure that consumers receive what they paid for.
