AWS Documentation mentions the following to support the above requirement:
Lifecycle configuration enables you to specify the lifecycle management of objects in a bucket. The configuration is a set of one or more rules, where each rule defines an action for Amazon S3 to apply to a group of objects. These actions can be classified as follows:
Transition actions – In which you define when objects transition to another storage class. For example, you may choose to transition objects to the STANDARD_IA (IA, for infrequent access) storage class 30 days after creation, or archive objects to the GLACIER storage class one year after creation.
Expiration actions – In which you specify when the objects expire. Then, Amazon S3 deletes the expired objects on your behalf.
For more information on S3 Lifecycle Policies, please refer to the URL below.

A built-in feature exists to do this job, hence Options A, B and C are not necessary.
