The engineer notices R1 stopped propagating any routes outside are 5. Which action must be taken to fix the problem?

Configure an additional filter-list on R1 for inbound traffic to allow external router into area 5.

Reconfigure the filter-list statement to apply in the inbound direction

Change the prefix-list action to permit and add an explicit deny statement for network 192.168.1.0/24

Add a permit statement for 0.0.0.0/0 le 32 to the end of the prefix-list 10 override the implicit deny.
