1. Lithium is used to make electrochemical cells.

2. Liquid sodium metal is used as a coolant in fast breeder nuclear reactions.

3. \mathrm{KOH} ( Potassium hydroxide ) is used in the manufacture of soft soap. It is also used as an excellent absorbent of carbon dioxide.

4. Caseium is used in deciding photoelectric cells.

So, (a) - (i), (b) - (iii), (c) - (i), (d) - (iv)
