D is the answer
Using the AWS Import/Export Service
To upload existing data to Amazon Glacier, you might consider using the AWS Import/Export service. AWS Import/Export accelerates moving large amounts of data into and out of AWS using portable storage devices for transport. AWS transfers your data directly onto and off of storage devices using Amazon’s high-speed internal network, bypassing the Internet.

Why not “A”
Upload archives in parts – Using the multipart upload API, you can upload large archives, up to about 40,000 GB (10,000 * 4 GB).
The multipart upload API call is designed to improve the upload experience for larger archives. You can upload archives in parts. These parts can be uploaded independently, in any order, and in parallel. If a part upload fails, you only need to upload that part again and not the entire archive. You can use multipart upload for archives from 1 byte to about 40,000 GB in size. For more information, see Uploading Large Archives in Parts (Multipart Upload).

Never mind the customer has only 1 MB bandwidth.. Hence “D” is right.

if this question comes up and snowball is an answer, select the snowball. Import/export is not the preferred method anymore.

1 Mbps it will take them 2.7 years to transfer 10Tb. So few weeks of shipping HD with AWS Import/Export will “provides the fastest method of
getting the data into Amazon Glacier”
