This is a question based on colligative property
colligative property is a property of solution which depends upon the number of molecules of solute and solvent
It is independent of nature of solute added to a particular solvent
The colligative properties are
a) elevation in boiling point
b) depression in freezing point
c) relative lowering of vapour pressure
d) osmotic pressure
As given we are adding same mount of each substance
Which means that we are adding same moles of each substance
the minimum number of particles will be produced by CH3OH (methanol) hence it will cause least temperature change.
The greatest change will be due to K3PO4
