C it is although I did not bother calculate this. The values I got were approximations.
1) -21<x<-20 or 20<x<21
2) x<2
We know from both combined that x must be some negative real number b/w -21 and -20

Yes C
1. We know x= +-20.63 so insufficient.
2. X<2. So Insufficient

Combining we know X = -20.63 and hence can find X^5.
