detailed solution

Correct option is A

$Ψ^{2}$ cannot be imaginary. $Ψ^{2}$ is positive for a real wave function and $Ψ^{*} Ψ$ (where $Ψ^{*}$ is the complex conjugate of $Ψ$ ) is positive.

The square of the wave function (i.e.,ψ²) at a point gives the probability density of the electron at that point.
