The complete option for the question

a.it depends on the self induced emf

b it depends on the inverse of the self induced emf

C.it depends on the current

d.it depends on the inverse of current

Answer is.it depends on the current

Explanation:

The energy stored in an inductor is W=1/2LI^2

From this equation it can be seen that energy in inductor L depends on current L

It depends on the current

Explanation:

The formula for the energy stored in an inductor is W =1/2 *L*I2

We can state that an electric current flowing in inductor , there is energy stored in the magnetic field. let consider the pure inductor L, and the power which is supplied to initiate the current in inductor.

consider the equation P = i*v

write the equation in terms of inductor.

P = L*i di/dt

P*dt = L*i di

rewrite the Energy equation W = \int_{0}^{t}P*dt

W = \int_{0}^{t} L*i di

by solving we will get the W = 1/2 *L*I2

From this information and formula we can state that he energy stored in an inductor depends on the current.
