According to the link, the collector-base capacitance is changed due to the change in the base collector voltage which, I believe, is correct. The base-emitter voltage (and consequently its capacitance) is little changed by the audio input voltage.If I understand FM modulators correctly, it's actually the B-E capacitance that is changed by the input signal. I think Collector cap. is changed very little.

I saw it somewhere that for the LC circuit to oscillate it needs feedback and the feedback must be greater than the unity. I want explanation on what this mean and the component responsible for the feedback. Thanks
What is meant is that the feedback loop gain is greater than unity. The transistor provides the gain for this.I saw it somewhere that for the LC circuit to oscillate it needs feedback and the feedback must be greater than the unity.

What FM transmitter, you've forgotten to attach the schematic.
