Explanation

Two actions are needed: (A) A bucket retention policy set to 7 years enforces a minimum retention period - objects cannot be deleted or overwritten before the policy expires, satisfying the regulatory compliance requirement directly at the storage level. (D) An object lifecycle policy that transitions objects from Standard Storage to a cheaper storage class (such as Coldline or Archive) after 3 years reduces cost for data that is rarely accessed, since those classes have lower per-GB storage prices. Option B (IAM Conditions) controls access but does not enforce retention. Option C (Object Versioning) protects against accidental deletion but does not enforce a retention period. Option E (Cloud Function) is a custom, less reliable, and operationally costly alternative to the native lifecycle policy.
