Which of the following is an example of a discriminative test using the In/Out test?

The In/Out test is designed to determine whether a sample meets specific criteria or specifications based on sensory attributes, making it a discriminative test. In this context, option B, which asks if a product meets specification, aligns perfectly with what the In/Out test aims to accomplish. This test focuses on discrimination between products by asking evaluators to decide whether the product either passes or fails to meet certain sensory quality standards.

Options such as identifying flavor intensity, measuring brightness, and evaluating texture focus more on quantifying characteristics rather than evaluating if a sample meets a predefined standard. These tasks lend themselves more to descriptive analysis or scaling tests rather than the binary yes/no decision-making characteristic of an In/Out test. Thus, recognizing the specific function of discriminative tests clarifies why option B is the most appropriate example in this scenario.
