Answer: $(3,1)$

Step-by-step explanation:

Given

The point C $(-3,-1)$ is rotated $180^{\circ}$ clockwise about the origin

If a point is rotated $180^{\circ}$ about the origin, then the sign of the co-ordinates changes without changing the order of coordinates.

So,C $(-3,-1)$ becomes C' $(3,1)$ after the rotation.
