In Cisco routers, to allow traffic from a specific source to a specific destination on a particular port, the access control list (ACL) needs to specify the source IP address, the destination IP address, and the destination port number that needs to be accessed. Since PC-1 with IP address 172.16.0.2 is trying to access the web server on port 8080 at IP address 192.168.0.5, the ACL applied inbound on SW2's G0/0 interface should permit traffic from PC-1 to reach the web server's specific port.
