In the circuit shown below between the terminal A and B an a.c. voltage source of frequency 400 Hz is connected. Another a.c. voltage of 1.0 MHz is connected between C and D. The output between E and F contains components at

• A. 400 Hz, 1MHz, 1000 4 kHz, 999 6 kHz
• B. 1 MHz, 1000 4 kHz, 999 6 kHz
• C. 400 Hz, 1000 4 kHz, 999 6 kHz
• D. 1000 4 kHz, 999 6 kHz
