well although i got this question, by studying griffith, but look what yousun wrote about choice C .. "it isn't continuous" but it is piecewise continuous, which is also acceptable for a wavefunction..
i am broaching this here, since due to some server reason i can't type in that site..

Re: 9277 #29
Nah, it's only acceptable for the derivative of the wavefunction, if/when the potential goes to infinity. The wavefunction itself must always be continuous. Just to make sure, I looked it up...blackcat007 wrote:but it is piecewise continuous, which is also acceptable for a wavefunction
Griffiths says:
"What are the appropriate boundary conditions for psi(x)? Ordinarily, both psi and (d/dx)psi are continuous, but where the potential goes to infinity, only the first of these applies."
