Option 2 : A + B = A.B
Concept:
De Morgan's Law: De Morgan's Law is also known as De Morgan's theorem, works depending on the concept of Duality.
- The complement of the product of 2 variables is equal to the sum of the compliments of individual variables. For example, (A.B)' = A' + B'.
- The complement of the sum of two variables is equal to the product of the complement of each variable. For example, (A + B)' = A'B
