Does local MWT require hidden variables?

[colorSpace]

A while ago I was having an interesting thread here about the possibility of local MWT, MWT as a local explanation of the entanglement experiments. In re-reading this discussion I was wondering whether the proposal of MWT as a local theory means:

a) Hidden variables are necessary but MWT claims to escape the common arguments against hidden variables by assuming multiple worlds.

b) Or MWT claims to explain the results locally even without hidden variables, using only superposition, interference, and multiple worlds as explaining concepts.

c) there are proponents of both ways of thinking.

MWI corresponds most closely to your option (b). The wavefunction being reality is meant to explain all the mysteries of quantum physics.
