The Scrum Master serves the Scrum Team by coaching them and the organization how to work empirically, which means using an evidence-based approach to inspect and adapt the product and the process. The Scrum Master also facilitates Scrum events as requested or needed, such as the Sprint Planning, the Daily Scrum, the Sprint Review, and the Sprint Retrospective. The Scrum Master ensures that these events are positive, productive, and kept within the timebox.
The Scrum Master does not resolve every impediment that the Developers run into, but rather helps them to remove or overcome those impediments themselves. The Scrum Master also does not never intervene in matters of the Scrum Team, but rather balances between providing guidance and allowing autonomy. The Scrum Master is not a passive observer, but an active servant leader who supports the team in achieving their goals.

Explanation
Explanation:
Technical debt is any shortcomings in the code. It is a natural by-product of software development (unavoidable) and can at best be managed. If neglected, it will compound and have a negative effect on the team's ability to the deliver value. A team can have an artificially high velocity by taking shortcuts or introducing technical, debt into the system. This can give a false assumption about the current state of the product. It can look good on the surface but underneath can be a mess.

Explanation
The best action for the Scrum Master to take in this situation is to conduct a session to help the Scrum Team resolve the conflict and create a uniform Definition of Done. This is because the Scrum Master is a servant-leader, a facilitator, and a coach to the team, who should have the skills to help resolve conflicts if called upon by the team1. The Scrum Master can employ various strategies to effectively resolve conflicts within the Scrum Team, such as promoting open communication, facilitating active listening, mediating disagreements, and fostering collaboration2. The Scrum Master can also remind the team members that conflicting ideas are natural and can be beneficial for innovation and learning, but making it personal does not help and violates the Scrum values of respect and openness3. The Scrum Master can guide the team to create a clear and shared Definition of Done that reflects their quality standards and expectations for the product4.
The other options are not the best actions for the Scrum Master to take, because they either undermine the self-organization and autonomy of the team, escalate the conflict, or avoid addressing the root cause of the problem.

In order to ensure transparency, work that must be done to the product must be visible in either the Product Backlog or the Definition of Done.

Getting the support from the business side helps facilitate the changes that fosters empiricism, self- organization, bottom-up intelligence, and intelligent release of software.
