The current flowing in two coaxial coils is in the same direction. If we increase the distance between the two , the electric current will,

$(a)\;\text{Increase} \\(b)\;\text{Decrease} \\ (c)\;\text{Remain the same} \\ (d)\;\text{can not be determined}$

As the distance between the two coils in increased the induced current in both the coils assist the main current , therefore current through each coil increases.
Hence a is the correct answer.
