Final answer:
Federal 'do not call' rules are regulations implemented by the FTC to limit telemarketing calls and protect consumers from unwanted solicitations.
Step-by-step explanation:
The true statement regarding federal 'do not call' rules is that they are regulations implemented by the Federal Trade Commission (FTC) to limit telemarketing calls and protect consumers from unwanted solicitations.
These rules require telemarketers to maintain a 'do not call' list and honor requests from consumers who do not wish to receive telemarketing calls. Violations of these rules can result in hefty fines and penalties for telemarketers.
