The minimum number of NAND gates required for implementing the Boolean expression AB + AB'C + AB'C' is:

Answer: B. 0AB + AB'C + AB'C' = A(B + B'C + B'C') = A(B + B'(C + C')) = A(B + B') = A. Since the expression reduces to a single input A, no NAND gate is required.

Correct answer: B

AB + AB'C + AB'C' = A(B + B'C + B'C') = A(B + B'(C + C')) = A(B + B') = A. Since the expression reduces to a single input A, no NAND gate is required.
