Loss of data during system retirement mitigated by validating migration procedures and keeping multiple backups is the correct option.

Retiring IT systems commonly produces the risk of data loss when migrations are incomplete or when data repositories are missed. Validating migration procedures confirms that data moved correctly and that dependent applications still function after the move. Keeping multiple backups gives you recovery points if the validation uncovers missing or corrupted data or if an unexpected problem appears during decommissioning. Together these steps directly reduce the likelihood of permanent data loss and align with the approach described in Loss of data during system retirement mitigated by validating migration procedures and keeping multiple backups.

Untracked service dependencies addressed by performing dependency mapping and using Cloud Asset Inventory is incorrect because it emphasizes discovering dependencies rather than preventing data loss. Dependency mapping is useful for planning the retirement but it does not by itself ensure that data is migrated or recoverable. The option also assumes cloud specific tooling which may not apply to all retirement scenarios.

Stakeholder resistance managed by immediately revoking user permissions is incorrect because abruptly revoking access is an operational action rather than a mitigation for the primary risk of data loss. Managing stakeholders usually requires communication and staged transitions to avoid business disruption and to ensure data is preserved during the retirement.

Lower power consumption solved by increasing server utilization is incorrect because reducing power use is an efficiency goal and not the common risk addressed when retiring systems. Increasing utilization may improve efficiency but it does not mitigate the key problem of preserving and validating data during decommissioning.
