Which type of establishments are subject to the Deceptive Trade Practices Act?

The Deceptive Trade Practices Act (DTPA) is designed to protect consumers from false, misleading, or deceptive acts or practices in the conduct of any trade or commerce. The correct answer encompasses a wide range of retail establishments, including grocery stores and car dealerships, all of which can engage in or be subject to deceptive trade practices. This broad applicability reflects the intent of the DTPA to cover various business types that deal with consumers in a retail context.

The act is not limited to specific types of businesses, such as just grocery stores or auto repair shops, but instead applies to any entity involved in the sale of goods or services to consumers. Therefore, businesses that operate in a multitude of sectors, including but not limited to grocery stores, car dealerships, and other retail outlets, fall under the jurisdiction of the DTPA. This ensures consumer protection across the board.

The other options imply a narrower scope of applicability that does not accurately reflect the comprehensive nature of the Deceptive Trade Practices Act. The DTPA's goal is to provide consumer protection broadly and equally to all businesses that engage in trade and commerce, thereby making option C the most accurate representation of which establishments are subject to the DTPA.
