Answer: Option (c) is the correct answer.

Explanation:

As density is mass divided by volume.

Mathematically, Density = $\frac{mass}{volume}$

So, more is the mass of a substance more will be its density but if volume is low then density will also have a low value.

Molar mass of neon is 20 g/mol.

Molar mass of $CO_{2}$ is 44 g/mol.

Molar mass of $Cl_{2}$ is 70.9 g/mol.

Since, $Cl_{2}$ molecule has the highest mass. Therefore, its density will also be high.

Thus, we can conclude that out of the given options $Cl_{2}$ gas has the highest density.
