Which outbound ACL applied to the WAN interface permits all traffic except HTTP sourced from 10.10.10.1?

The correct answer uses an extended ACL to specifically deny TCP traffic from host 10.10.10.1 with a destination port of 80 (HTTP). The subsequent permit ip any any statement is crucial because ACLs have an implicit "deny any any" at the end. Without this explicit permit, all other traffic would also be blocked. Option 1 is incorrect because eq 80 any incorrectly specifies the destination port as the source port. Option 2 is incorrect because any eq 80 incorrectly specifies the source port as the destination port. Option 3 is incorrect because it lacks the necessary permit ip any any statement, which would result in all other traffic being denied.
