Solution

The correct options are
C
$O_{3}$

D
$C l_{2}$

Heteroatomic molecules (compounds) are those which are made up of different kinds of atoms. As $H_{2} O$ is made up of two different atoms i.e. hydrogen and oxygen and similarly $H_{C} l$ is made up of hydrogen and chlorine but $O_{3}$ and $C l_{2}$ are made up of same types of atoms so they are homoatomic molecules (elements).
