Final answer:
Acceptance testing is conducted to verify that a product meets regulatory requirements. This type of testing ensures that a product complies with industry-specific standards and regulations. Other types of testing focus on functionality and interaction between parts but not on regulatory compliance. Correct answer is D. Acceptance testing.
Step-by-step explanation:
The type of testing that is normally conducted to verify that a product meets a particular regulatory requirement is D. Acceptance testing. Acceptance testing is a formal testing process that determines whether a system satisfies certain criteria set by the stakeholders, which often includes regulatory standards or industry-specific requirements. This type of testing is critical when products must comply with regulations, such as medical equipment in healthcare settings, where they must ensure not only functional correctness but also adherence to safety and privacy regulations.
Unit testing, integration testing, and system testing are also important in the development lifecycle, but they focus on verifying that individual parts of a software product work in isolation (Unit testing), together with each other (Integration testing), or as a complete system (System testing), respectively, rather than specifically ensuring regulatory compliance. So, the correct answer is D. Acceptance testing.
