6. Identify the most simple POS
expression which generates
the K-map shown.

- (A+C')(A+B+C)
- (A+B)(A+C')(B+C')
- (A'+B')(A'+C)(B'+C)
- (A'+C)(A'+B'+C')
- (A+B)(A'+C)(B'+C)

4 is WRONG. Here's how to do it:
1. Draw a K-map for F.
2. Group 0-entries to obtain SOP expression for F'
3. Complement resulting expression to give a POS expression
for F (SOP complemented yields POS)
