C is the answer. https://cloud.google.com/architecture/migration-to-google-cloud-transferring-your-large-datasets#storage-transfer-service-for-large-transfers-of-on-premises-data Like gsutil, Storage Transfer Service for on-premises data enables transfers from network file system (NFS) storage to Cloud Storage.

C is the Answer as we need weekly run Storage transfer service has the feature to schedule.

The fact that it's about a POSIX source makes necessary the set up of Storage Transfer Service agents. This detail limits [C] to be the correct answer, since it's the data center hosting the files where the agent must be installed. -- Some excerpts: (an older version of documentation was definite) "The following is a high-level overview of how Transfer service for on-premises data works: 1.Install Docker and run a small piece of software, called an agent, in your private data center. " Source: https://web.archive.org/web/20210529161414/https://cloud.google.com/storage-transfer/docs/on-prem-overview -- "Storage Transfer Service agents are applications running inside a Docker container, that coordinate with Storage Transfer Service to read data from POSIX file system sources, and/or write data to POSIX file system sinks. If your transfer does not involve a POSIX file system, you do not need to set up agents." Source: https://cloud.google.com/storage-transfer/docs/managing-on-prem-agents
