I think this negative sign has been confirmed from the MSB and LSB bits of the given number and not the 1's complement number.
After finding answer through the appropriate orocedure as discuss above, check the given number, and give the particilar +ve or -ve sign to the answer. Thats it.

The negative number always represent in 2's complement form. So after calculating 2's complement of the above binary number, it is always negative. So the D option is correct.

There is no carry bit. If the carry bit present it will be positive or else it will be negative.
