Who should make sure everyone on the scrum Team does their tasks for the sprint?

According to the Scrum Guide, the Scrum Team should make sure that everyone on the team does their tasks for the Sprint, as they are collectively accountable for creating valuable Increments that meet stakeholder needs and expectations. The other options are not valid, as they imply that someone else outside the Scrum Team (such as a project manager) or another role on the Scrum Team (such as the Product Owner or the Scrum Master) is responsible for making sure that everyone does their tasks for the Sprint.
