Answer - **B.**

Degree of generator polynomial is $3$ hence $3-bits$ are appended before performing division

After performing division using $2$'$s$ complement arithmetic remainder is $011$

The remainder is appended to original data bits and we get $M' = 11001001\bf{011}$ from $M = 11001001.$

m + r + 1 < 2^{r}

messege, m = 8 bits

8 + 1 + 1 > 2^{1}

8 + 2 + 1 > 2^{2}

8 + 3 + 1 > 2^{3}

8 + 4 + 1 < 2^{4}

Hence r = 4

then sending mesg is 8 + 4 = 12 bits
