Solution

The correct option is D $Δ^{2}$
$r_{1} r_{2} r_{3} = \frac{k}{r}$
$\Rightarrow \frac{Δ}{(S - a)} \times \frac{Δ}{(s - b)} \times \frac{Δ}{(S - c)} = \frac{k}{r}$
$\Rightarrow \frac{S Δ \times Δ^{2}}{S (S - a) (S - b) (S - c)} = \frac{k}{r}$
$\Rightarrow \frac{S Δ \times Δ^{2}}{Δ^{2}} = \frac{k}{r}$
$\Rightarrow Δ S r = k$
$k = Δ S \times \frac{Δ}{S}$
$∴ k = Δ^{2}$
