I think a remove curse always removes a curse, regardless of what kind of curse it is. Otherwise, what would be the point? But unless the curse is also lifted from the treasure itself, the moment you touch the treasure again, you are cursed again. So I would go with A.
You know, I agree with this thought, in concept. BUT, where's the danger in taking a mummy lords treasure if a 3rd level spell can negate the curse just like any other curse?
