$"Option 4"$ is the only viable answer.

Explanation:

YOu have been given the chemical equation:

$H_2(g) + Cl_2(g) rarr 2HCl(g)$

There are 2 equiv (moles if you like) of gaseous product, and 2 equiv gaseous reactant. Clearly, mass is conserved in a chemical reaction, as are pressure and volume in this scenario, because temperature was specified to be constant. $"Option 4"$ is the only starter.
