Solution

The correct option is E
Statement 1 is correct but statement 2 is not correct.

Statement 1: Addition of the oxidation numbers of all the elements in the formula of a compound must be 0.
For example, in water molecule, each H atom has oxidation number of +1 and oxygen atom has oxidation number of -2.
Addition of the oxidation numbers of all the elements in $H_{2} O = 2 (+ 1) - 2 = 0$
Statement 2: Generally oxidation number of oxygen is -2 for most of the compounds. There are certain compounds in which the oxidation number of oxygen is not -2.
For example, in hydrogen peroxide $H_{2} O_{2}$ , the oxidation number of oxygen is -1.
Both the statements 1 and 2 are correct.
