Refer to the graphic. A named access list called chemistry_block has been written to prevent users on the chemistry network and public Internet from access to the records server. All other users within the school should have access to this server. The list contains the following statements:

permit 172.16.0.0 0.0.255.255 172.16.104.252 0.0.0.0

Which of the following command sequences will place this list to meet these requirements?
Hera(config)# interface e0
Hera(config-if)# ip access-group chemistry_block in
Hera(config)# interface s0
Hera(config-if)# ip access-group chemistry_block out
Apollo(config)# interface s0
Apollo(config-if)# ip access-group chemistry_block out
Apollo(config)# interface s1
Apollo(config-if)# ip access-group chemistry_block in
Athena(config)# interface s1
Athena(config-if)# ip access-group chemistry_block in
Athena(config)# interface e0
Athena(config-if)# ip access-group chemistry_block out
54.

RouterA(config)#interface loopback 0
RouterA(config-if)# ip address 192.168.31.33 255.255.255.255
It creates a virtual, software only, interface.
It uses a wildcard mask of 255.255.255.255.
It ensures than an interface is always active for OSPF processes.
It provides a way to test the convergence of OSPF routing updates.
The mask of 255.255.255.255 is called a host mask.
