The MSB (Most Significant Bit) is 1, so this is a negative number in 1’s complement. , 11110100 (in 1’s complement) = -11 (decimal).

In question, they have said that it is a signed number so no need to search for a sign as we know that sign bit is placed as MOST SIGNIFICANT BIT so just reverse bits 0 to 1 and 1 to 0 or just subtract the whole binary bit with all 1's then you will get 00001011 whose value is 11.
Since the MSB is 0 given decimal equivalent is positive.
Since the MSB is 0 given decimal equivalent is positive.

Can somebody please explain how to solve using 1's complement in detail?

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.
So the answer has to be -11.

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

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