Three solenoid coils of same dimension, same number of turns and same number of layers of winding are taken. Coil 1 with inductance was wound using a Mn wire of resistance ; Coil 2 with inductance was wound using the similar wire but the direction of winding was reversed in each layer; Coil 3 with inductance was wound using a superconducting wire. The self inductance of the coils are

Options:

Answer:
A
Solution:

Self-inductance (L) of a solenoid where absolute permittivily of space/ number of turns in the coil area of cross-section of the solenoid length of solenoid This expression shows that for all three solenoids, the self-inductances will be equal.
