* Development (Developers)- Provides insights on feasibility and technical constraints.
* Testing (Testers, QA)- Ensures testability, acceptance criteria, and risk identification.

* (B) is incorrectbecause architecture is part of development, but not the primary driver of user stories.
* (D) is incorrectbecauseacceptance testing is a process, not a stakeholder group.
