Solution

The correct option is B $Δ H_{s o l n}$
Stanolard enthalpy of solution is when, $1$ mole of a substance is dissolved at constant temperature and pressure.
For example: $N a C l (s) ⟶ N a C l (a q)$
Here, $1$ mole of $N a C l$ at constant $T$ and $P$ is converted from solid to aqueous state. Thus it is $△ H$ solution $^{⊝}$ .
