In case of $d_{x^2-y^2}$ orbital:

In case of $d_{x^2-y^2}$ orbital probability of finding the electron is maximum along x and y-axis

The $d_{x^2-y^2}$ orbital's lobes are positioned at a 45-degree angle between the axis. Therefore, at a 45-degree angle between the x and y axes, the discovery of an electron in a $d_{x^2-y^2}$ orbital is highest.
