NAND gates are preferred over others because these__________________?
Correct answer: B. can be used to make any gate
- A. have lower fabrication area
- B. can be used to make any gate
- C. consume least electronic power
- D. provide maximum density in a chip
Explanation
A NAND gate is a universal gate because combinations of NAND gates can implement NOT, AND, OR, and hence any Boolean function. Its main advantage in this question is universality, not necessarily minimum power or area.
