The scope of a use case specification is defined as:

• A. The environment where the system operates
• B. The entity that owns (provides) the use case
• C. The time constraints
• D. The external interfaces

Answer: (B)

Defining the scope through the owning entity establishes who is responsible for the use case and what area of the system it covers. The owner provides the use case, sets its boundaries, and ensures it aligns with business goals, making it clear who approves changes, what content is included, and how the use case will be maintained. This ownership basis is what gives the specification its real-world limits and accountability.

Environment describes context, not ownership; time constraints are about deadlines and timing rather than boundary definition; external interfaces concern how the system talks to others, which is about interaction details rather than who owns the use case.
