What it the main reason for the Scrum Master to be at the Daily Scrum?
A . To gather status and progress information to report to management.
B . To write down any changes to the Sprint Backlog, including adding new items, and tracking progress on the burn-down.
C . He or she does not have to be there; he or she only has to ensure the Development Team has a Daily Scrum.
D . To make sure every team member answers the three questions.

Answer: C

Explanation:

The correct answer is C, because the Scrum Guide states that “the Scrum Master ensures that the Development Team has the meeting, but the Development Team is responsible for conducting the Daily Scrum. The Scrum Master teaches the Development Team to keep the Daily Scrum within the 15-minute time-box.” Therefore, the main reason for the Scrum Master to be at the Daily Scrum is to ensure that it happens, but he or she does not have to be there.
