Which probe prevents a slow-starting container from being killed before it finishes initialising?

1. A Liveness probe with a short period
2. ✓ B Startup probe with a generous failureThreshold (correct answer)
3. C Readiness probe only
4. D No probe

Shortcut: The startup probe suspends liveness and readiness checks until it succeeds, so a long initialisation does not trigger repeated restarts.
