Solution

The correct option is C zero
Here, voltmeter is connected across the ideal ammeter. Ideal ammeter has zero resistance so as to measure accurate current in circuit. Due to zero resistance ammeter will read total current in circuit, without dropping any current in its circuitry. The voltmeter measures the voltage of component across which it is connected in parallel. Hence, the voltage across ammeter is
$V = I R$
$V = I (0) = 0 V$
