Model Answer

(A) Each appliance gets the full supply voltage

In a parallel circuit, each appliance is connected across the live and neutral wires, so all appliances receive equal (full) potential difference of 220 V.

Explanation

The textbook explicitly states: "In order that each appliance has equal potential difference, they are connected parallel to each other." This is the primary reason. Option B is wrong — parallel connection actually increases total current. Options C and D are unrelated to why parallel connection is used.
