C) If assertion is true but reason is false.
D) If the assertion and reason both are false.
E) If assertion is false but reason is true.
Correct Answer: C
Solution :
The manner in which the two coils are oriented, determines the coefficient of coupling between them. \[M={{K}^{2}}.{{L}_{1}}{{L}_{2}}\] When the two coils are wound on each other, the coefficient of coupling is maximum and hence mutual inductance between the coil is maximum.
