Explanation:
The correct answer is C. This solution meets all the requirements: it uses an S3 Lifecycle policy to transition the records from S3 Standard to S3 Glacier Deep Archive after 1 year, ensuring the records are immediately accessible for the first year and then archived for the remaining 9 years. Additionally, S3 Object Lock in compliance mode is used to prevent any deletion of the records for the entire 10-year period, even by administrative users and root users. This also ensures maximum resiliency and durability for the stored records.
