b. place theory
volley principle
d. auditory principle

C. volley principle

Explanation:

The Voley Principle (also called the Voley Theory) was proposed by the research team of Ernest Weaver and Bray Bray in the 1930s as a complementary part of the theory of hearing frequency. This principle mainly states the individual fiber groups (neurons) of the auditory system respond to a sound stimulus with successive impulses (also called volleys) that are activated to match these stimuli.

These impulses are action potentials fired slightly out of phase between each one. So, when combined, a higher sound frequency can be encoded and this signal sent to the brain.  

It is important to note that experimentaly it was tested that this only happens with sounds with frequencies between 500 Hz and 5000 Hz.

i think so it’s will be b yes i believe its

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
