fc-fm= 10 difference left side band.
fc+fm=10 difference right sideband.
fc+fm=10 difference right sideband.

Actually question is given half.
The Tuned -Circuit of the oscillator in an AM transmitter uses a 50 micro H Coil and 1 nF capacitor. Now if the oscillator output is modulated by audio frequency upto 10khz, then find the frequency range occupied by the sidebands.

How this be happen? Kindly tell us. Where you got L and C?

Where did you get the 50 mH, as well as L and C from? Please, explain.

I think the solution is wrong, but. I think you can still see the correct answer because OPTION B, among all the choices only has the frequency range of 2 x 10 kHz.

bw = 2 * 10 khz = 20khz.
Again,
722khz - 702khz = 20 khz.
So, option B is right.
Again,
722khz - 702khz = 20 khz.
So, option B is right.

How it's done? Kindly explain to us from where you got L and c values.

Yes, option B correct. The difference between an upper frequency and lower frequency for all remaining options doesn't satisfy.

Here, L=50 uH and C=1nF.
