Lesser than that of water vapour in the air

A-B interactions are stronger than A-A and B-B interactions.

A-B interactions are weaker than A-A and B-B interactions.

A-B interactions are equal to A-A and B-B interactions.

The solution behaves ideally.

$A - B$ attraction force is greater than $A - A$ and $B - B$

$A - B$ attraction force is less than $A - A$ and $B - B$

$A - B$ attraction force remains same as $A - A$ and $B - B$

Volume of solution is different from sum of volume of solute and solvent

$A - B$ attraction force is greater than $A - A$ and $B - B$

$A - B$ attraction force is less than $A - A$ and $B - B$

$A - B$ attraction force remains same as $A - A$ and $B - B$

Volume of solution is different from sum of volume of solute and solvent

Relative lowering of vapour pressure is independent of the solute and the solvent.

The relative lowering of vapour pressure is a colligative property.

Vapour pressure of a solution is lower than the vapour pressure of the solvent.

The relative lowering of vapour pressure is directly proportional to the original pressure.
