The answer is option A To effectively track the Sprint progress, Scrum mandates Preparing Sprint burn down charts

Explanation:

Sprints are time-boxed periods of one week to one month, during which a product owner, scrum master, and scrum team work to complete a specific product addition. During a sprint, work is done to create new features based on the user stories and backlog. A new sprint starts immediately after the current sprint ends.

Some scrum teams deploy new product features for use at the end of each sprint. For scrum teams with a release with every sprint, the time to market is simply the sprint length, measured in days.

A sprint burn down chart shows the progress the development team is making and is a powerful tool for visualizing progress and the work remaining.
