Correct answer is option (c). Because A peroxide is a compound containing oxygen oxygen single bond. The way you can identify it when it is in a compound is by using the valence electron of the partner substance i.e., the metal or hydrogen. let us take an example of sodium peroxide (Na2O2). We know that sodium has a valency of 1. If it were to bond to oxygen, the compound should contain one oxygen atom and two sodium atoms. When you look at a peroxide of sodium, you find that it contains two oxygen atoms. This suggests that each sodium is bonded to one oxygen atom and since oxygen has a valency of 2, then the extra electron in each oxygen is used to bond the oxygen atoms and thereby attaining stability.
