- a)-37 as 1101 1011
- b)-89 as 1010 0111
- c)-48 as 1110 1000

Take 2's complement of binary no given. Convert the 2's complement to its decimal equivalent. It should match the give number but no sign
e.g 2's complement of 1101 1011 is 0010 0101 which is equal to 37
and similarly for other options..but for C
for option c, 2's complement is 00011000 which is equivalent to 40 and not 48. Hence c is a wrong option
