I would go with 8 grams as well, it seems like the most reasonable option given the dilution.

I'm not sure, but I think it might be 12 grams based on the volume of the solution.

I agree with A, the concentration of potassium permanganate in the solution is lower so it should be less than 14 grams.

I think it's 8 grams because of the dilution factor in the solution.
