Subdividing [0, 1] into 10 equally spaced intervals of length 
gives the partition
![[0,1] = \left[0,\dfrac1{10}\right] \cup \left[\dfrac1{10},\dfrac2{10}\right] \cup \cdots \cup \left[\dfrac9{10},1\right]](https://tex.z-dn.net/?f=%5B0%2C1%5D%20%3D%20%5Cleft%5B0%2C%5Cdfrac1%7B10%7D%5Cright%5D%20%5Ccup%20%5Cleft%5B%5Cdfrac1%7B10%7D%2C%5Cdfrac2%7B10%7D%5Cright%5D%20%5Ccup%20%5Ccdots%20%5Ccup%20%5Cleft%5B%5Cdfrac9%7B10%7D%2C1%5Cright%5D)
The 
-th subinterval has left and right endpoints, respectively, given by
where 
.
The midpoint of the -th interval is the average of these,
We approximate the area under 
over [0, 1] by the Riemann sum,
(D)
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.
