Solution

The correct option is C $a < 0$
Given the graph of quadratic expression $y = a x^{2} + b x + c$ as shown:

Upon observing the graph, we see that the graph is an downward opening parabola $\Rightarrow a < 0$
Also, the graph is cutting the $x -$ axis at two distinct points.
$\Rightarrow D > 0$
