According to the Agile Practice Guide and the Scrum Guide, Scrum is defined by three specific categories: Roles, Artifacts, and Events (also called Ceremonies).

Defining " Events " : The team member correctly pointed out that the " events " are missing. In Scrum, there are five formal events for inspection and adaptation: The Sprint, Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective.

Daily Scrum (Option A): A 15-minute event for the Developers to synchronize activities and create a plan for the next 24 hours.

Sprint Retrospective (Option C): An event held at the end of the sprint to plan ways to increase quality and effectiveness by inspecting how the last Sprint went with regards to people, relationships, processes, and tools.

Coaching the Team: The Scrum Master’s role is to ensure the team understands the framework. By identifying these missing events, the team completes the " heartbeat " of the Scrum process, allowing for the empirical process control of transparency, inspection, and adaptation.

Analysis of other options:

Option B (Increments): This is an Artifact, not an event. The Increment is a concrete stepping stone toward the Product Goal.

Option D (Sprint backlog): This is an Artifact, not an event. It is the set of Product Backlog items selected for the Sprint, plus a plan for delivering them.

Option E (Product backlog): This is an Artifact, not an event. It is an emergent, ordered list of what is needed to improve the product.

Per PMI standards, when a team is organizing their approach and identifies that events are missing, they must select from the timeboxed activities defined in the framework, such as the Daily Scrum and the Sprint Retrospective.
