Answer:
Kinesics
Step-by-step explanation:
The theory of Kinesics was developed by Ray L. Birdwhistell. According to this theory, kinesics is the study of body movements. In other words, it can be defined as an interpretation of non-verbal behavioral movements.
Birdwhistell claimed that all body movements or postures are not accidental, hence, they have the meaning of their own.
In the given case, wrinkling of the nose, according to the theory, is an example of kinesics, because wrinkling of the nose conveys the meaning that the food smelled bad.
