B. No
C. Yes, and each Scrum Team’s performance may be affected by how much they participate during
the Sprint as a Scrum Master or Product Owner.

Answer: C

Explanation:

Every Scrum team only can have a Product Owner and a Scrum Master. The Product Owner is one person, not a committee. The Product Owner may represent the needs of many stakeholders in the Product Backlog.
