Quizplus · Accepted Answer

The resonant frequency of the circuit can be calculated using the formula: 
f = 1 / (2π√(LC))

where L is the inductance and C is the capacitance of the circuit.
Given values are: L = 2 mH and C = 20 nF
Substituting these values in the formula, we get:
f = 1 / (2π√(2 mH * 20 nF))
f ≈ 0.25 kHz.

Therefore, the best option is B, 0.25 kHz.
