Solution

The correct option is A $- \frac{s}{r}$
Given, $p (x) = r x + s, r \neq 0$ .

We know, $a$ is a zero of $f (x)$ , only if $f (a) = 0$ ,
i.e. to find the root, we have to find $x$ .

Then, $p (x) = 0$
$ $\Rightarrow r x + s = 0$
$\Rightarrow r x = - s$
$\Rightarrow x = \frac{- s}{r}$ .

Therefore, option $A$ is correct.
