Can trigger your desire for a specific type of food.
a. appetite
b. satiety
c. hunger
d. food intake

A. appetite.

Explanation:

Appetite is a concept with a long tradition in the sciences and in philosophy, which makes it complicated to define it briefly, either as a corporeal or spiritual (related to the mind) capacity. However, if one follows Baruch Spinoza in his masterful treatment of the tendency called appetite, it does not matter where it originates, but what it does, and what it does specifically is to incline, in a conscious manner, a person towards the attainment or possession of a singular and specific thing. As such, it can be said that appetite, related only to food, would be the desire to eat a specific thing and not just any thing.
