Correct answer: O, S, P, F

Explanation

To configure OSPF area 4 as a totally stubby area, you need to apply the area 4 stub command to all routers in the area and on the ABR, use the area 4 stub command with the no-summary keyword. The other options, while related to OSPF configurations, do not specifically contribute to making the area totally stubby.
