Answer
The maximum energy stored in the inductor is $~~6.88\times 10^{-9}~J$
Work Step by Step
In part (a), we found that the maximum energy stored in the capacitor is $~~6.88\times 10^{-9}~J$
Since this is the total energy in the system, there will be times during the oscillation when all of this energy is stored in the inductor.
The maximum energy stored in the inductor is $~~6.88\times 10^{-9}~J$
