* Apex Trigger (Option B):
* An Apex trigger can be written on theContainer__cobject to prevent deletion unless theStatus__cfield value is "Decommissioned".
* This allows custom logic to be executed during the deletion process.

Validation Rule (Option D):
A validation rule is typically used to enforce conditions during record creation or update. However, it cannot directly restrict deletions.
To ensure deletion restriction, an Apex trigger is more effective.
Not Suitable:
Option A(Before record-triggered flow): Flows triggered "before delete" are not available.
Option C(After record-triggered flow): These occur after a record is deleted, so they cannot prevent the deletion process.
