Solution

The correct option is B Bending copper pipe as a coil helps to increase the surface area for heating.

The outer surface of the copper tube and inner walls are painted black to increase the absorption of heat to produce high temperatures. Moreover, when it is fixed in the form of a coil in a box the surface area available for absorption is increased.
