Answer is A.(true).
Here, the MSB Value '1' indicates the negative sign.
Remaining value = 0011100 which is in 2's complement form.
w.k.t, 2's complement = 1's complement +1.
Therefore, the value of 1's complement is =0011011
final value = 1100100 which is equal to the value of 100 (10*10 (decimal) = 1010*1010 (binary)).
