Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
An ideal voltmeter must have resistance infinity, so that all the voltage that it measures is across the terminals, instead of losing some in voltmeter circuitry.
Hence assertion and reason both are correct and reason is correct explanation of assertion.
