Question

A particle is subjected to a potential described as follows:
$V(x) = \begin{cases} \infty, & \text{if } x \leq 0 \\\ V_0, & \text{if } a \leq x \leq b \\\ 0, & \text{elsewhere} \end{cases}$
Here, $a > 0$ and $b > a$. If the energy of the particle $E < V_0$, which one of the following schematics is a valid quantum mechanical wavefunction ($\Psi$) for the system?

• A.
• B.
• C.
