D.Use Lifecycle policies to move the data onto Amazon Simple Storage service after a period of 3 months

Answer - B and C
The AWS Documentation mentions the following
Amazon Simple Storage Service (Amazon S3) makes it simple and practical to collect, store, and analyze data - regardless of format – all at massive scale. S3 is object storage built to store and retrieve any amount of data from anywhere – web sites and mobile apps, corporate applications, and data from IoT sensors or devices.

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.
