Solution

The correct options are
A $CaO$ is solid.
B $H_{2} O$ is liquid.
D ${Ca(OH)}_{2}$ forms a solution with water
The conventions (s), (l), (g), (aq) represents solid, liquid and solution in water.
In the equation,

$CaO (s) + H_{2} O (l) \to Ca {(OH)}_{2} (aq) + H eat$

$∙$ $CaO$ is mentioned as (s), hence it is in solid state.

$∙$ $H_{2} O$ is mentioned as (l), hence it is in liquid state and not in vapour state.

$∙$ ${Ca(OH)}_{2}$ is mentioned as (aq), hence it forms a solution with water.
