Solution :
A) The correct option is vapour pressure lowering.
The relative vapour pressure lowering is directly proportional to the mole fraction of solute particles.
Other coligative properties do not depends upon the mole fraction of solute particles.
B) The correct option is Ba(OH)2
Barium hydroxide is a strong base, it is strongly ionized in water, hence highly soluble.
AgOH is almost insoluble salt, while Pb(OH)4 and Cu(OH)2 is weakly insoluble in water.
C) The correct option is Ag+
Ag+ forms weak base in water, hence it acts as a weak acid in water.
Other cations are act as strong acids.
D) The correct option:
Rate = K [A] [B]
Because for heterogeneous equilibrium, the rate will depend upon the concentration of both reactants (A and B).

What is the relationship between the moles of solute and the
mass of solute?
Rewrite the molality expression in terms of grams and molecular
weight.
Background:
Properties that depend on the concentration of particles in solution are called colligative properties. The number of particles in a solvent can affect the freezing or boiling point of solvent. To express the effect of concentration on freezing point or boiling point, molality is used in place of molarity. Molality (m) is the number...
