Capacitor with a Capacitive Reactance of 21.21m ohm at 6.66KHz. Does this capacitor appear as a short circuit ?

Loaded question. If the 'other' components in the circuit are resistive and greater than an ohm or so, then yes. It would be considered as a 'nearly' short circuit.
OTOH, if it's in parallel with an inductor having an inductive reactance of 21.21m ohm at 6.66KHz, it's a parallel resonant circuit and it looks like a 'nearly' infinite (or open) circuit.
Hope that helps ☺

I'm not sure this question is complete.
With a capacitive reactance of 21.2 MOhm at 6.66KHz, it is certainly not a short circuit for a signal that's ~6KHz. At lower frequencies, the resistance would be even higher, and at higher frequencies, the resistance would be lower.
At a high enough frequency, it would appear as a short circuit.
