Detailed Solution

Concept: Heat is produced on an electrical conducting wire when current is conducted through it. By using the Joule heating process, the heating element transforms electrical energy into heat energy. The heating element is utilised to prevent wire formation. For this technique, the current's direction makes no difference.
Electric appliance heating elements are made from nichrome. Because nichrome has a greater melting and boiling point than metals, it does not easily oxidised or burn at high temperatures. Thus, even when a significant quantity of heat is generated as a result of current flow, it does not melt.
Heating components like electric heaters, electric rod, electric iron, etc. are made from nichrome.
because nichrome does not oxidise and has a very high resistance.
As a result, choice 2 is right.
