Answer: (B)

Backflow prevention devices are critical components in water supply systems, designed to prevent contaminated water from flowing back into the clean water supply. To ensure they function correctly and effectively, testing is required at regular intervals. The standard frequency for testing backflow prevention devices is annually. This yearly testing helps to verify that the devices are in proper working order and compliant with applicable safety regulations. Regular testing also aids in identifying any necessary repairs or replacements that may be needed to maintain system integrity and protect public health. Therefore, annual testing is a standard practice supported by plumbing codes and public health guidelines.
