Answer:
B
Step-by-step explanation:
The correct answer would be option B.
Orbicular oris is a muscle that runs around the outside of the mouth. It is the muscle responsible for changing the shape of the mouth during different actions such as talking, whistling, and kissing.
Depending on the intensity of the kiss though, some other muscles in the body might get involved as a result of other actions such as the movement of the head, the wagging of the tongue, etc. However, the primary muscle during kissing remains the orbicularis oris muscle.
Hence, the correct option is B.
