D Correct answer
Explanation

For Amplitude Shift Keying (ASK), a binary modulation scheme, one signal element (symbol) carries exactly one bit. Therefore, the baud rate (symbol rate) equals the bit rate. With a 1200 bps bit rate, the baud rate is also 1200 baud. This relationship (bit rate = baud rate) holds for all binary modulation schemes including BPSK and FSK.
