MCQ (Single Correct Answer)

-0.6

For a binary half-sub-tractor having two inputs A and B, the correct set of logical expressions for the outputs D (=A minus B) and X (=borrow) are

$$D = \,AB + \overline A \,B,\,X = \overline A \,B$$

$$D = \,\overline A \,B + A\overline B + A\overline B ,\,X = A\overline B $$

$$D = \,\overline A \,B + A\overline B ,\,X = \overline A \,B$$

$$D = \,AB + \overline A \,\overline B ,\,X = A\overline B $$
