The exact extract describes a safety-management phase where management makes safety commitments, safety personnel act as a deterrent, rules and procedures are established, and safety supervision plus accident control are emphasized. This clearly matches Supervision and management. In this phase, safety is no longer handled only by instinct or informal personal judgment. Instead, the organization begins to rely on formal rules, management commitments, safety personnel, supervision, and accident-control mechanisms. It is still not the highest maturity level, because employees may not yet be fully self-driven or team-driven in safety behavior. “By instinct” would mean safety behavior depends mainly on individual reactions and basic survival awareness. “Self-management” means employees voluntarily manage safety without heavy supervision. “Team management” means safety is embedded in collective team behavior. The statement specifically emphasizes supervision, rules, deterrence, and accident control, so the correct classification is supervision and management.
