Can a Scrum Master or a Product Owner also serve as a Developer on a Scrum Team?
A . No
B. Never
C. Yes

Answer: C

Explanation:

This is not prohibited by the Scrum Guide. It can be hard to wear "two hats". It can be difficult to fully attend to all expectations of the Scrum Master or the Product Owner role, while also being a focused Developer of the Scrum team. It can be helpful to understand more of the development work. It can also be a pitfall.
