20% is the same as saying 0.2, so if you multiply 0.2 by 240, you should get your answer. Or an alternate way of seeing it is 2 times 24.
we are given

Firstly, we will factor numerators and denominators

we can see that
n^2 -6 is factor on both numerator and denominator
so, it will get cancelled
and n^2 -6 can not be equal to 0
so, one of restriction is


we can simplify it

we know that denominator can not be zero


so, option-B.......Answer
The correct answer is 196 or Option A.
The explanation is just as complicated as the question.
