Could somebody please explain to me the difference between flavour and mass eigenstates.

The question is "Neutrinos can be produced from charged pion decay, What
force is involved, and at the time of creation is the neutrino in a flavour or
mass eigenstate, and why?"

And why would it be in one of these states at creation?

Cheers Guys!
