Solution

The correct option is A $01$
01 is the 1's complement of 10.

The ones' complement of a binary number is defined as the value obtained by inverting all the bits in the binary representation of the number (swapping 0s for 1s and vice versa). ... In such a system, a number is negated (converted from positive to negative or vice versa) by computing its ones' complement.
