The correct options are
B (-3,0)
C (2,0)
The perpendicular distance of a point from the x-axis is the ordinate of the point.
On the coordinate plane, points are written in the form of (abscissa, ordinate).
Those points whose ordinate is zero lies on the x-axis.
Since, the points (-3,0) and (2,0) have ordinate zero, they will lie on the x-axis.
