Question

Assertion : A wire carrying an electric current has no electric field around it.
Reason : Rate of flow of electron's in one direction is equal to the rate of flow of protons in opposite direction.

• A. If both the assertion and reason are true and reason explains the assertion.
• B. If both the assertion and reason are true but reason does not explain the assertion.
• C. If assertion is true but reason is false.
• D. If assertion is false but reason is true.
