The correct option is B Tactile
Vibrissae are the long, bristle-like hairs that project from the snout or brow of most of the mammals, such as the whiskers of a cat or rat. Vibrissae often serve as tactile organs i.e., the sensory organ that detects the motion of the other animals especially in nocturnal animals and marine mammals, such as seals.
Thus, the correct answer is option A.
