ISRO | ISRO CS 2014 | Question 15

Consider the logic circuit given below:

(A) A’C + BC ‘ + CD
(B) ABC + C’D
(C) AB + BC’ + BD’
(D) AB’ + AC’ + C’D

Answer: (C)
Explanation: F = (((CD)’B)'(AB)’)’
F = ((CD)’B)” + (AB)”
F = (CD)’B + AB
F = (C’ + D’)B + AB
F = C’B + D’B + AB
F = AB + BC’ + BD’

So, option (C) is correct.
