Let's have a look at the access list 104: The question does not ask about ftp traffic so we don't care about the two first lines. The 3rd line denies all telnet traffic and the 4th line allows icmp traffic to be sent (ping). Remember that the access list 104 is applied on the inbound direction so the 5th line "access-list 104 deny icmp any echo-reply" will not affect our icmp traffic because the "echo-reply" message will be sent over the outbound direction.
