Final answer:
The consumer group is the Better Business Bureau (BBB), which promotes trust and ethical business practices, while the FTC is a government agency protecting consumers from fraud and overseeing antitrust regulations.
Step-by-step explanation:
The consumer group that requires affiliated businesses to follow a code of business practices is the Better Business Bureau (BBB). Unlike the Federal Trade Commission (FTC) which is a federal agency created to enforce antitrust legislation, defend consumers from fraud, and oversee competition in various sectors of the economy, the BBB is a non-profit organization that promotes trust among consumers and businesses. It provides business reviews, dispute resolution services, and requires companies that are accredited by them to adhere to established standards of business practices.
