The correct answer is D. The cultural meaning of illness
Explanation:
In societies, cultural meaning refers to the ideas, definitions, beliefs, etc. people in their culture have about some aspect or situation. In the case of the cultural meaning of illness, it refers to the ideas, beliefs, etc. related to a condition or illness and that is not based on medicine but in all beliefs, personal experience, and similar.
The case presented is an example of the cultural meaning of illness because due to people observing mostly gay men die and due to their lack of knowledge they understood HIV as the "gay cancer" rather than as a sexually transmitted disease that can affect anybody which means people created ideas, beliefs, etc. about this disease that was related to the culture and also to personal beliefs or prejudice.
