MCQ (Single Correct Answer)

-0.3

For the identity AB+$$\overline A $$ C + BC= AB + $$\overline A $$ C, The dual form is

(a+b)($$\overline A + c$$)(b+c)=(a+b)($$\overline A $$+C)

($$\overline A + \overline B )(A + \overline C )(\overline B + \overline C ) = \overline {(A} \, + \overline B )(A + \overline C )$$

$$(A + B)(\overline A + C)(B + C) = (\overline A + \overline {B)} (A + \overline C )$$

$$\overline A \,\overline B + A\,\overline C + \overline B \,\overline C = \,\overline A \overline B + A\,\overline C $$
