Final answer:
A consumer advisory should be provided for TCS food that (c) is raw or undercooked to alert consumers about the potential risk of foodborne illness.
Step-by-step explanation:
A consumer advisory should be provided for menu items that contain TCS food that is raw or undercooked. Time/temperature control for safety (TCS) food includes a variety of items that require certain time and temperature controls to prevent unsafe bacterial growth. Advisories are particularly important for foods such as raw or undercooked meats, dairy products, and certain vegetables that carry a higher risk of foodborne illness.
While very spicy food, food containing gluten or made with non-big-eight allergens can be a concern for some consumers due to preferences or specific dietary needs (like in the case of celiac disease), they do not inherently require a consumer advisory for food safety reasons. However, good practice includes providing clear information on all potential allergens to ensure informed choices by customers with food sensitivities or allergies.
