Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point-to-point or point-to-multi point communication channel.

Baud rate : means the number of times a signal in a communication channel changes its state.

Bit rate : is a measure of the number of data bits (0's and 1's) are transmitted in one second.

The baud rate will be lower than the bit rate by the factor of bits per symbol. That is, if there are 4 bits per symbol, the baud rate will be that of the bit rate. This confusion came because the early analog telephone modems weren't very complicated, so bps was equal to baud.

That is, each symbol encoded one bit. Later, to make modems faster, communications engineers invented increasingly clever ways to send more bits per symbol. So the Answer is Option : B.

But here only digital transmission so only bit rate will be used so E is the correct answer.
