  1. The message 11001001 is to be transmitted using the CRC polynomial x3 + 1 to protect it from errors. The message that should be transmitted is
    1. 11001001000
    2. 11001001011
    3. 11001010
    4. 110010010011
Correct Option: B

The message P(x) = 11001001
Divisor, D(x) = 1001
CRC Remainder = 011
Therefore, the transmitted message comes out to be – 11001001011
