Correct answer & explanation

AWS Database Migration Service (DMS)
AWS DMS is designed for migrating databases to AWS, including to Redshift. Option A (AWS Snowball) is for large data volumes (petabytes) and not efficient for <1 TB. Option C (Amazon S3 Transfer Acceleration) speeds up uploads to S3 but not directly to Redshift. Option D (AWS Direct Connect) is a network connection, not a migration service.
