Assertion: Electric appliances with metallic body e.g., heaters, presses etc., have three pin connections, whereas an electric bulb has a two pin connection. Reason: Three pin connections reduce heating of connecting cables.

Options

  1. AIf both A and and Reason are true and Reason is the correct explanation of Assertion.
  2. BIf both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. CIf Assertion is true but Reason is false.
  4. DIf Assertion is false but Reason is true.

Correct answer

C. If Assertion is true but Reason is false.

Step-by-step solution

The third pin is used for grounding purposes so that it leaves the user safe while handling the appliance by making the extra charge on it get discharged.
