The formula for energy stored in an inductor is given by:

E = (1/2)L*I^2

where E is the energy stored, L is the inductance, and I is the current flowing through the inductor.

Rearranging this formula, we get:

I = sqrt(2*E/L)

Substituting the given values, we get:

I = sqrt(2*393 J / 1.2 H) = 25.6 A

Therefore, the answer is (C) 25.6 A.
