Three solenoid coils of same dimensions, same number of turns and same number of layers of windings are taken. Coil 1 has inductance L1 wounded by Mn wire of resistance 6 $$\Omega$$m$$-$$1, coil 2 with inductance L2 wounded by similar wire but in reverse direction in each layer. Coil 3 with inductance L3 wounded by a superconducting wire. The relation between their self inductances will be

A
L1 = L2, L3 = 0
B
L1 = L2 = L3
C
L1 = L3, L2 = 0
D
L1 > L2 > L3
