What is the general minimum initial mass threshold required for a star to become a Type II supernova progenitor?

Answer

Greater than about eight times the mass of the Sun ($8 M_{\odot}$)

Stars generally considered to be those starting with masses greater than about eight times the mass of the Sun are the ones that undergo core collapse to become Type II supernovae.
