Well now that almost everyone agrees with option B, why doesn't someone advocate for option A?
If we are lead to believe that the entity/god has no free will with respect to this choice then their claim becomes credible.
If their claim is credible then the question occurs about whether subjecting oneself to a nightmare and removing suffering or not do so.
As I said above this is a common disagreement between theories of the Good and theories of the Right.
Imagine something Good like pleasure, happiness, welfare, etc...
By sacrificing all your claim on this something Good you can force the entity to bestow everyone else with sufficiently unlimited quantities of this Good.
Theories of the Good claim the moral choice is the one that maximizes the total Good.
Theories of the Good would claim option A is the only moral choice.
