Solution which have only one volatile components, The vapour pressure of volatile component in a given solution can be written by -
${\mathrm{P}}_1={\mathrm{x}}_1{\mathit{P}}_1^0$
If we compare the equations for Raoult's law and Henry's law, $\left(\mathrm{P}={\mathrm{K}}_{\mathrm{H}}\cdot \mathrm{x}\right)$, only proportionality constant ${\mathrm{K}}_{\mathrm{H}}$ differes from ${\mathit{P}}_1^0$.
Thus,
Rault's law becomes a special case of Henry's law in which ${\mathrm{K}}_{\mathrm{H}}$ becomes equal to ${\mathit{P}}_1^0$.
All other options are wrong for Roult's law.
