Ans, Option D - C6H10O4

In the compound, Weight of Carbon = 72 g (approx), weight of Hydrogen = 10 g (approx), weight of Oxygen = 64 g (approx) .

Respective atomic masses of C, H and O are 12, 1 and 16.

So, atoms of C, H and O combined are 72/12 = 6; 10/1 = 10 and 64/16 = 4 respectively.

Hence, the formula.
