Correct Answer: Option D

Explanation

resonance frequency \(f_r\) = \(\frac{ 1}{ 2\pi \sqrt{LC}}\)

                                   \(f_r\) = \(\frac{1}{2\pi \sqrt{5\times10^{-6} \times 8\times 10^{-3}}}\)

                                    \(f_r\) = \(\frac{1}{ \pi 0.0004}\)  

                                     \(f_r\) = \(\frac{ 2500}{\pi}\)
