D.
None of these​

Answer 1

$d) \: is \: the \: correct \: answer$

Answer 2

The correct answer is option (B.) Impedance of the circuit is high.

Explanation:

• When Q-factor of a circuit is high, then Impedance of the circuit is high.
• Q factor is alternatively defined as the ratio of a resonator's centre frequency to its bandwidth when is subject to an oscillating driving force.
• These two definitions give numerically same, but not identical, results.
• Higher Q represents or indicates a lower rate of energy loss and the oscillations die out more slowly.
• Hence, the correct answer is option B. i.e Impedance of the circuit is high.
