My understanding is, "rely 255/255" means the interface is not reliable at all. I think none of the choices is correct. How do you pick?

Refer to the exhibit. What does the 255/255 value in the output represent?

A#show int s0/0
Serial0/0 is up, line protocol is up (connected)
Hardware is HD64570
Internet address is
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec, rely 255/255, load 1/255
-output omitted-

1. the number of times that the link was operational during 255 polls
2. the link failure rate over 255 seconds
3. the probability that the link will continue to be operational
4. a static value representing the normal reliability of an interface type
