Equally compression between cylinders......
Hi there!
We can use implicit differentiation with respect to x:

If a term with 'y' is differentiated, a 'dy/dx' must be included.
We can differentiate each term separately for the explanation.
<u>3xy</u>
We must use the power rule since 'x' and 'y' are both in this term.
Power rule:


Now, we can do the others.
<u>4x</u>
This is a normal power rule derivative.

<u>y²</u>
Since we are not differentiating with respect to y, we must include 'dy/dx'.

Combine the above:

Rearrange to solve for dy/dx.
Move dy/dx to one side:

Factor out dy/dx and divide:

Answer:
Option-C
Explanation:
The primary auditory cortex is a collection of neuron present in the superior temporal gyrus of the temporal lobe.
The neurons which are the fundamental unit of a nervous system in the primary cortex of the brain are specialized to interpret and discriminate the components or elements of sounds.
The neurons can categorize the elements of the sound into their specific frequency i.e they can categorize the elements like pitch and loudness of sound which have different frequencies.
Thus, Option-C is the correct answer.
