Show answer & explanation
Correct answer: C
Given: f(A,B,C) = Σm(0,1,3,7)
Step 1: Write the minterms as product terms.
m0 (000) = A'B'C'
m1 (001) = A'B'C
m3 (011) = A'BC
m7 (111) = ABC
Step 2: Combine terms by factoring (or use a Karnaugh map).
Combine A'B'C' + A'B'C = A'B'(C' + C) = A'B'.
Combine A'BC + ABC = BC(A' + A) = BC.
Final simplified expression: A'B' + BC
This can be verified by checking that the simplified expression covers minterms 0, 1 (via A'B') and 3, 7 (via BC) and does not include other minterms.
