    ASSERTION: Higher the range, greater is the resistance of ammeter.
    REASON: To increase the range of ammeter, additional shunt needs to be used across it.

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.

    C) If assertion is true but reason is false.

    E) If assertion is false but reason is true.
