Correct answer: permit tcp host 209.165.200.225 eq 80 host 209.165.201.25.
Why this is the answer
The correct statement is permit tcp host 209.165.201.25 host 209.165.200.225 eq 80. This ACL entry permits TCP traffic from the source host (client 209.165.201.25) to the destination host (web server 209.165.200.225) on destination port 80. The eq 80 operator specifies the destination port. The option permit tcp host 209.165.200.225 lt 80 host 209.165.201.25 incorrectly reverses the source and destination and uses lt (less than) instead of eq (equal to) for the port. The option permit tcp host 209.165.200.225 eq 80 host 209.165.201.25 incorrectly places the destination port after the source host. The option permit tcp host 209.165.200.225 host 209.165.201.25 eq 80 incorrectly reverses the source and destination IP addresses.
