Just substitute (1-x) in place of x in each solution

only in option D we get the original function equal to new one.

just continue ur calculation

(1-x)^2 (1-(1-x))^2 ==> (1-x)^2 (1-1+x))^2

==>(1-x)^2 (x)^2 --> this eqn is same as f(x)

hope this clears ur doubt.......pls revert in case of doubt........ :wink:
