Assertion : During reverse biasing a diode doesn't conduct current. Reason : It narrows the depletion layer.

Assertion : During reverse biasing a diode doesn't conduct current. Reason : It narrows the depletion layer.
  1. both $A$ and and Reason are true and Reason is the correct explanation of Assertion.
  2. both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
  3. Assertion is true but Reason is false.
  4. Assertion is false but Reason is true.

Solution

During reverse biasing, the depletion layer widens, and so there is more resistance for an electron or a hole to cross that layer to conduct current.
