Colligative properties are used for the determination of:

Equimolar solutions in the same solvent have

Match the items given in Column-$I$ (method used for determining colligative property) and Column-$II$ (the corresponding colligative property) and find the correct order.

Column-$I$	Column-$II$
$A$. Beckmann method	$1$. Osmotic pressure
$B$. Ostwald-Walker method	$2$. Elevation in $B$.$P$.
$C$. Berkeley-Hartley method	$3$. Depression in $F$.$P$.
$D$. Landsberger method	$4$. Relative lowering of vapour pressure

Identify the colligative property from the following options.

Which is not a colligative property?
