Correct Answer is D
The AWS Documentation mentions the following
AWS Snowball is a service that accelerates transferring large amounts of data into and out of AWS using physical storage devices, bypassing the Internet. Each AWS Snowball device type can transport data at faster-than internet speeds. This transport is done by shipping the data in the devices through a regional carrier. The devices are rugged shipping containers, complete with E Ink shipping labels. With a Snowball, you can transfer hundreds of terabytes or petabytes of data between your on-premises data centers and Amazon Simple Storage Service (Amazon S3).
Option A is incorrect since there is a lot of data to be transferred and using the Internet VPN connection would not be ideal
Option B is incorrect since there is no mention in the question of on-going data transfer. So setting AWS Direct connect just for a one time transfer might not be so reasonable
Option C is incorrect since this is used for connecting VPC’s together
