Answer:
Option D
Explanation:
Here 'g' is the inverse of f(x)
$\Rightarrow$ fog(x)= x
On differentiating w.r.t x , we get
$f'\left\{g(x)\right\}\times g'(x)=1$
$g'(x)=\frac{1}{f'(g(x))}=\frac{1}{\frac{1}{1+\left\{g(x)\right\}^{5}}}$
$ [ \because f'(x)=\frac{1}{1+x^{5}}]$
$g'(x)=1+\left\{g(x)\right\}^{5}$
