A diode detector is used to detect an amplitude demodulated wave of \( 60 \% \) by using a condenser of capacity \( 250 \mathrm{pF} \) in parallel with a load resistance 100 kilo ohm. Find the maximum modulated frequency which could be detected by it.
(a) \( 20.62 \mathrm{MHz} \)
(b) \( 10.62 \mathrm{MHz} \)
(c) \( 7.31 \mathrm{MHz} \)
(d) \( 5.31 \mathrm{kHz} \)
