(When multiple Scrum Teams are working on a single product, what best describes the Definition...

The correct answer is A. When multiple Scrum Teams work on the same product, they should share a common Definition of Done. This creates transparency across the product and ensures that all Increments are held to the same quality standard. Without one shared Definition of Done, it becomes difficult to inspect the integrated product accurately and determine whether work is truly complete.

Option B is incorrect because Scrum does not recommend separate Definitions of Done later reconciled in a hardening Sprint. Hardening Sprints are not part of Scrum and usually indicate that quality has not been built into normal development. Option C is also incorrect because merely making different definitions visible does not solve the inconsistency problem. A product needs one integrated standard of completion. Option D is incorrect because Scrum Masters do not define the Definition of Done on behalf of the teams. It must be mutually understood and used by the Scrum Teams working on that product, taking organizational standards into account.

A shared Definition of Done supports integration, quality, and releasability. It helps all teams contribute to one coherent product Increment rather than producing partially compatible outputs with differing completion standards.
