Answer:
The correct answer is letter "A": expanded the FTC's authority to regulate advertising.
Step-by-step explanation:
The U.S. Wheeler-Lea Act of 1938 is a federal law that was passed to empower the Federal Trade Commission (FTC) Act of 1914. The Wheeler-Lea Act gave the FTC power to issue cease-and-desist orders and fines to companies engaging in deceiving trade practices and marketing. Before this amendment, the FTC had the power to regulate violations related to commerce and advertising committed by industry competitors.
