Assertion (A) If $a_1, a_2, \ldots, a_n$ are the $n$ distinct roots of the equation $x^n-2=0$, then $1+\left(1-a_1\right)\left(1-a_2\right) \ldots \left(1-a_{n-1}\right)\left(1-a_n\right)=0$

Reason (R) If $\alpha_1, \alpha_2, \ldots, \alpha_n$ are the roots of $f(x) \equiv p_0 x^n+p_1 x^{n-1}+p_2 x^{n-2}+\ldots+p_n=0$, then the roots of

$$ f(g(x))=0 \text { are } \mathrm{g}^{-1}\left(\alpha_i\right), i=1,2,3, \ldots, n $$

The correct option among the following is

A

(A) is true, (R) is true and (R) is the correct explanation for (A).

B

(A) is true, (R) is true but (R) is not the correct explanation for (A).
