Given binary number is 010111.1100

1's compliment = change 0's into 1, 1's into 0.
so, 1's compliment= 101000.0011

2's compliment = 1's compliment + 1

i.e., 101000.0011

Let's convert it to 1's complement.

Change 0 to, 1 to 0.

So 1's complement is 101000.0011.

To get the 2's complement just add 1 from the 1's complement
101000.0011 + 1 = 101000.0100.

So B is the answer.
