Assuming a constant bit depth, why does typical analog audio encoded using a 192

Question

Assuming a constant bit depth, why does typical analog audio encoded using a 192 kHz sample rate sound superior to the same audio encoded at 8 kHz? In the higher-quality analog signal, a larger number of distinct amplitude levels were encoded O In the higher-quality analog signal, a larger number of amplitude changes were encoded. OIn the higher-quality analog signal, a smaller number of distinct amplitude levels were encoded O In the higher-quality analog signal, a smaller number of amplitude changes were encoded None of these answers are correct

Explanation / Answer

Sampling rate determines how many times the aplitude of a sound wave is recorded in a second. Thus more the number of times the amplitude is recorded per second, more is the number of aplitude changes recorded and hence better is the quality of sound.

Thus correct answer is : In the higher-quality analog signal, a larger number of amplitude changes were recorded.
