Solution

The correct option is C $C O, C O_{2}$
The law of multiple proportions say that If two elements form more than one compound between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers. The ratio of the masses of oxygen that can react with 100 grams of carbon is $266 : 133$ , i.e. $2 : 1$ , a ratio of small whole numbers in $C O$ and $C O_{2}$ .
