A source produces binary data at the rate of 10 kbps. The binary symbols are represented as shown in the figure.

The source output is transmitted using two modulation schemes, namely Binary PSK (BPSK) and Quadrature PSK (QPSK). Let and B2 be the bandwidth requirements of BPSK and QPSK respectively. Assuming that the bandwidth of the above rectangular pulses is 10 kHz, B1 and B2 are
A. B1 = 20 kHz, B2 = 20 kHz
B. B1 = 10 kHz, B2 = 20 kHz
C. B1 = 20 kHz, B2 = 10 kHz
D. B1 = 10 kHz, B2= 10 kHz
