Solution

The correct option is C Statement $1$ is not correct, but Statement $2$ is correct
$△ H_{s u b}^{\circ} = △ H_{f u s i o n}^{\circ} + △ H_{v a p}^{\circ}$
Enthalpy is a state function ,similarly $△ H_{s u b}^{\circ}, △ H_{f u s i o n}^{\circ}, △ H_{v a p}^{\circ}$ are also state functions
Statement 1 is false,but statement 2 is true.
