If a person is born blind, in what way do the senses of hearing and touch improve? a. The person gradually develops more receptors in the ears and skin. b. The number of receptors does not change, but each of them becomes more responsive to weak stimuli. c. The receptors in the ears and skin send faster action potentials to the brain. d. Through practice the person learns to increase attention to hearing and touch, and those sensations come to activate the occipital cortex.

People who are born blind in life have more nuanced sense of hearing, their sense of hearing are very strong specially when it comes to musical abilities or tracking moving objects around them for example: imagine crossing a busy road using sound alone.
Hearing is the basic or strong sense for blind people. So, when they are looking at a movie, it depends upon their hearing to follow it.
People who are blind, they really do have enhanced abilities in their other senses. Blind individuals had heightened senses of hearing, smell and touch as compared to the people who were not blind. It shows neural responses that reflect both the motion and the frequency of auditory signals in blind individuals. The blind people has to play an analogous role by tracking or moving auditory objects, such as cars, or the footsteps of the people around them.
