Solution :-

One of the reacting compounds must always contain an element that can exist in at least three oxidation states in disproportionation reactions.

(a) Because these elements can exist in three or more oxidation states, disproportionation reactions can occur.

(b) Because these elements can exist in three or more oxidation states, disproportionation reactions can occur.
