Solution

The correct option is A $- \frac{5}{2}$
Here, $p (x) = 2 x + 5$ .
In order to find zero of $p (x)$ , we equate $p (x)$ to 0,
i.e $p (x) = 0$ .
$\Rightarrow 2 x + 5 = 0 \Rightarrow 2 x = - 5 \Rightarrow x = \frac{- 5}{2}$ .
$∴ \frac{- 5}{2}$ is the zero of $p (x)$ .
Therefore, option $D$ is correct.
