Consider
point is $$P$$.
Here,
the ordinate is $$0$$ or $$y = 0$$.
Also,
the point is at a distance of $$2$$ units right of the $$y$$-axis.
So,
its abscissa will be $$+2$$.
Therefore, the point lies on the $$x$$-axis.
Hence,
the co-ordinates of the required point are $$P(2,0)$$.
Consider point is $$Q$$.
Here,
the abscissa is $$0$$ or $$x = 0$$.
Also,
the point is at a distance of $$3$$ units above the $$x$$-axis
So,
its ordinate will be $$+3$$.
Therefore, the point lies on the $$y$$-axis.
Hence,
the co-ordinates of the required point are $$Q(0,3)$$.
Consider
point is $$R$$.
Here, t he
point is at a distance of $$2$$ units left of the $$y$$-axis.
So,
its abscissa will be $$-2$$.
Also,
the point is at a distance of $$1$$ unit above the $$x$$-axis.
So,
its ordinate will be $$1$$.
Therefore, the point lies in the $$\text{II}^{nd}$$ quadrant.
Hence, the co-ordinates of the required point are $$R(-2,1)$$.
Consider
point is $$S$$.
Here,
the point is at a distance of $$3$$ units left of the $$y$$-axis.
So,
its abscissa will be $$-3$$.
Also,
the point is at a distance of $$2$$ unit below the $$x$$-axis.
So,
its ordinate will be $$-2$$.
Therefore, the point lies on the $$\text{III}^{rd}$$ quadrant.
Hence, the co-ordinates of the required point are $$S(-3,-2)$$.
Therefore, the only point that lies on the $$x$$-axis is $$P(2,0)$$.
Hence,
option $$A$$ is correct.
