The maximum radial probability in $1 \mathrm{s}$-orbital occurs at a distance when: $[{\mathrm{r}}_0=\mathrm{Bohr} \mathrm{radius}]$

Consider following figure $\mathrm{A}$ and $\mathrm{B}$ indicating distribution of charge density (electron probability ${\mathrm{\Psi }}^2$) with distance $\mathrm{r}.$

Select the correct statement:

Consider the following statements:

$\left(\mathrm{a}\right)$ Electron density in the $\mathrm{XY}$ plane in $3{\mathrm{d}}_{{\mathrm{x}}^2-{\mathrm{y}}^2}$ orbital is zero

$\left(\mathrm{b}\right)$ Electron density in the $\mathrm{XY}$ plane in $3{\mathrm{d}}_{{\mathrm{z}}^2}$ orbital is zero.

$\left(\mathrm{c}\right)$ $2\mathrm{s}$ orbital has one nodal surface.

$\left(\mathrm{d}\right)$ $2{\mathrm{p}}_z$ orbital, $\mathrm{XY}$ is the nodal plane.

From the above statements, which are incorrect statements?
