The correct answer to this question is A; the oxidation number of Hydrogen in KH is -1. A few general rules apply when assigning oxidation numbers: a few of these include the oxidation number of an atom in an element is zero, and the algebraic sum of the oxidation numbers in the formula of a compound is zero.

Generally, Hydrogen in compounds has an oxidation number of +1, although in metal hydrides such as NaH, LiH, and KH, its number is -1. Additionally, the only oxidation number for potassium (symbol K) in a simple inorganic compound is +1; therefore the oxidation number of hydrogen in KH is -1.
