Option A: Amalgam of mercury in sodium
Amalgam is formed when a liquid metal (Hg) dissolves in solid metal (Na).
So this is liquid in solid.
(A) → (III)
Option B: An alloy
Alloy is a solid solution of one metal in another.
Example: Copper in gold
(B) → (IV)
Option C: Saturated solution of KCI
KCl is solid and dissolves in water (liquid).
So this is solid in liquid.
(C) → (I)
Option D: Chloroform in nitrogen gas
Chloroform vapour dissolves in nitrogen gas.
So this is liquid in gas.
