Which organization is responsible for establishing standards for messaging in SMS/MMS Compliance?

The correct choice is B, as the CTIA, or the Cellular Telecommunications and Internet Association, is the organization that establishes standards for messaging in SMS/MMS compliance. The CTIA plays a crucial role in developing best practices and guidelines for mobile messaging to ensure that it is used responsibly and ethically. Their standards help protect consumers and ensure that messages are sent in compliance with regulations, thereby fostering trust in mobile communications.

The other organizations mentioned, while influential in their respective areas, do not specifically focus on SMS/MMS compliance. The FCC (Federal Communications Commission) primarily regulates interstate and international communications by radio, television, wire, satellite, and cable, while the FTC (Federal Trade Commission) focuses on consumer protection and preventing anti-competitive business practices. The AMA (American Marketing Association) is involved with marketing principles but does not govern SMS/MMS messaging standards.
