Answer:
Option (a) is correct.
is a perfect cube.
Step-by-step explanation:
Given : Some Monomial
We have to choose out of given monomial that is a perfect cube.
Perfect cubes are numbers that can be written as 
So, consider
, we know 1 can be written as 
Thus,
can be written as 
Thus, Option (a) is correct.
G(a/2)= 2(a/2)-3
=2a/2-3
then just subtract 2a/2 by 3/1 by finding the common denominator and same for the next one.
