Answer:

A. It has two complex roots.

Explanation:

We are given that

Discriminant of an equation =negative

We have to find which is true about the equation .

Let quadratic equation

ax^2+bx+c=0

Discriminant=
D=b^2-4ac

If D < 0 , then the equation has complex roots.

Therefore, if the discriminant of an equation is negative then the equation has two complex roots.

Answer:A. It has two complex roots.
