A) 1 B) 2 C) 3 D) 4

Explanation / Answer

ANSWERS:

11- X=AC+B
12-D) 2,4,8
13-B) provides a means of reducing complex boolean expression
14-X=A'B' + AB
15-XNOR as it produces AB + A'B' which is the expression for XNOR gate.
17-(A'B)(AC+C'D)
18-4 gates 2 for AND operation 1 for OR operation and 1 for inverting
