Explanation:
It would be 6 because of the elements
Hydrogen Peroxide slowly decomposing into water and oxygen increases the entropy of the universe. Any reaction of a system always increases the degree of the orderliness of the universe.

look at the chemical tables. but i believe it is A
Salt makes the freezing point of water decrease, so it would freeze at a warmer temperature than regular water
