The switching expression corresponding to f (A,B,C,D) = Σ(1, 4, 5, 9, 11, 12) is:
- A.
BC'D' + A'C'D + AB'D
- B.
ABC' + ACD + B'C'D
- C.
ACD' + A'BC' + AC'D'
- D.
A'BD + ACD' + BCD'

Show answer & explanation
Correct answer: A
To verify the switching expression, check if it evaluates to 1 for minterms 1, 4, 5, 9, 11, and 12. The correct expression simplifies to BC'D' + A'C'D + AB'D, which matches the required minterm list exactly.
