Solution

The correct option is A 1 Molal solution
It expresses the amount by which the boiling point $T_{b}$ of a solvent is raised by a nondissociating solute, through the relation

${Δ T}_{b} = K_{b} \times m$ .

where,
$m$ is the molality of the solute.
$K_{b} =$ an elevation in boiling point produced by 1 molal non-electrolytic solute solution.

Hence, the correct option is $A$
