Why minus sign there?

In bcd MSB is 1 -> negative.

Incase MSB is 0 -> positive.

Its answer is - 11 as the MSB is 1. Please can anyone check my answer? And let me know if I am wrong.

Thanks.

1's compliment of 11110100 is 00001011. MSD is 0 means a positive number. And 00001011 is equal to decimal 11 (option c).

In case of signed 1's compliment sign bit which is MSB bit should remain unchanged so signed one's compliment of 11110100 is 10001011.

So the answer has to be -11.
