The comparison is not between the mouse’s nose and the human nose; it is between the nerve lining of a mouse’s nose and the nerve lining of a human nose. C brings it out by saying  that of.  Therefore, C is so far so good.

However, I do not know why C calls it a human’s nose; human is a possessive adjective and to make it doubly possessive by adding apostrophe s is unnecessary. Probably the author wants to equate the term human with man as a noun

C... The mouse's nose is compared to a human's nose.

dvinoth86 · Answer

Elements compared are the number of olfactory receptors in human's nose and in mouse's nose.  we are not comparing verbs.  hence eliminate A,B,E. 
Between C and D, I prefer  C.  
D is illogical comparison.

paragkan · Answer

Also, we can eliminate A and B right away because they use 'that' for comparison. 'As' is better for comparison than 'that'
Between the remaining, D & E are illogically constructed. So, C is the only option left.

I do agree that C's construction is a bit awkward but it happens to be the best alternative provided

B. that human noses do ' That' refers to olfactory receptors. We want something that refers to 'number of receptors' 
C. as that of a human's nose  Clearly refers to number of olfactory receptors.  
D. as those of a human  comparison is done with human 
E. as human noses do  number is compared with human noses
