Answer
2.
Breaking the given 18 bits into 9 bits
1 1 1 0 0 0 1 0 0
1 1 1 1 0 0 1 0 0
As, the number of 1's in 1st one is even and 2nd one is odd, the 1st one is the correct one.
So, the correct word gives 11000100, after duplicating it shuld be 1100010011000100
So the hexadecimal number should be C4C4.
