Which action will DECREASE cost without compromising user accessibility?

Explanations:

Changing the EBS volume to Provisioned IOPS (PIOPS) may improve performance but will increase costs further, as PIOPS is typically more expensive than standard EBS volumes.

Storing the video in an Amazon S3 bucket and creating an Amazon CloudFront distribution would reduce costs by offloading traffic from EBS to S3 and utilizing CloudFront’s caching capabilities, which provides faster content delivery and reduces data transfer costs.

Splitting the video into smaller segments may improve load times for users but does not inherently reduce costs. In fact, it could increase complexity and costs due to additional requests and data management.

Clearing S3 buckets in each Region and uploading the videos could lead to higher costs due to increased data transfer and management overhead. This does not efficiently address the high access costs associated with the original video content.
