The answer is C. For those who think it's B because of the Glacier, take note that it is the ORIGINAL file that is moved to Glacier, not the CONVERTED file.

C. Amazon Elastic Transcoder uses pipelines to manage transcoding jobs. When you create a job, you specify the pipeline that you want to submit the job to. Pipelines are closely tied to an S3 bucket that you specify.

You are moving the original video to glacier which is high in size and will increase cost. You will server your users the transcoded video which is still on S3 So C is the correct answer for me
