ω = 2πf.
Therefore, f = 2000/2 =1000 Hz ; f = 4000/ 2 = 2000 Hz.
Upper Sideband = carrier frequency + modulating frequency.
(1) 1 MHz + 1 kHz = 1.001 MHz.
(2) 1 MHz + 2 kHz = 1.002 MHz.
Answer: Option [B].
Therefore, f = 2000/2 =1000 Hz ; f = 4000/ 2 = 2000 Hz.
Upper Sideband = carrier frequency + modulating frequency.
(1) 1 MHz + 1 kHz = 1.001 MHz.
(2) 1 MHz + 2 kHz = 1.002 MHz.
Answer: Option [B].

Yes, right as higher frequencies are called. So it should be fc+nfm.
