Solution

The correct option is A

We know that if quadratic equation is given in form $a x^{2} + b x + c$ Then sum of the roots of the equation is $\frac{(- b)}{a}$ . Product of roots of the equation is $\frac{c}{a}$ . Comparing the given equation with the standard form of equation we find that (s) $\times$ (t)= $\frac{s}{p}$ .
