Solution

The correct option is B negative number
For a quadratic polynomial : $a x^{2} + b x + c$ ,
a is called the quadratic coefficient.

If a > 0 , then the graph of the quadratic polynomial will be an upward opening parabola.

If a < 0, then the graph of the quadratic polynomial will be a downward opening parabola.
