The correct answer is C because gsutil offers object composition or parallel upload capabilities to manage the upload of larger files efficiently. This method involves splitting a large file into smaller parts, uploading them in parallel, and then recomposing them in the cloud, which significantly speeds up the transfer process. This can be enabled by setting the parallel_composite_upload_threshold option in gsutil.

• Option A is incorrect because recursive uploads are designed for handling folders and subfolders, not for speeding up the transfer of large individual files.
• Option B is incorrect as the Cloud Transfer Service does not support uploads from on-premises data centers.
• Option D is incorrect because multi-threaded options are more suited for uploading multiple files simultaneously to better utilize bandwidth, not for accelerating the transfer of a single large file.
