In given Combinational logic, X is given by

A

$$X = A \overline{B} \overline{C} + \overline{A} B \overline{C} + \overline{A} \overline{B} C + ABC $$

B

$$X = \overline{A} B C + A \overline{B} C + A B \overline{C} + \overline{A} \overline{B} \overline{C} $$

C

$$X = AB + BC + AC $$

D

$$X = \overline{A} \overline{B} + \overline{B} \overline{C} + \overline{A} \overline{C}$$
