The answer to this is C. There are four tablets that are needed in order to create the needed solution. For those who are not aware, potassium permanganate is a type of solution that was first created to be a disinfectant. Over the past years, there are more uses for it that were found.

This is being used to treat different skin conditions. There are also different fungal infections that can be cured with the use of this tablet. This should not be exposed to too much heat as it can produce deadly fumes that will be toxic to a lot of living things. This can also react to some flammable materials.
