Correct Answer: There is a violent explosion
Solution : The correct option is - There is a violent explosion
A strong combustion reaction happens when glycerol or glycerin is combined with solid potassium permanganate (KMnO₄). When in contact with glycerol, potassium permanganate, an extremely strong oxidant, instantly explodes. The rate of oxidation of the glycerol causes heat to be produced faster than it can be expelled.
