Answer:
B. 11110111
Explanation:
Binary representation of number 9 = 00001001
Binary representation of -9 would involve calculating the twos complement representation of 00001001
First we compute the ones complement of this number by reversing the bits.
00001001 => 11110110
Next we calculate the twos complement representation by adding 1 to the ones complement.
11110110+1 = 11110111
So the final representation is 11110111.
