The ammeter, voltmeter and, resistors `R_(1)` and `R_(2)` connected in the circuit as shown below have been checked and found to be correct.
On plugging the key, the voltmeter reads 4.5 V but the ammeter reads 1.5 A. This is most likely because the wires joined to :

Options

A. resistor `R_(1)` are loose
B. resistor `R_(2)` are loose
C. both the resistors `R_(1)` and `R_(2)` are loose
D. ammeter terminals are loose

Answer
