Answer: D
Top-down testing starts with the system's major functions
and works downwards. The initial emphasis when using
prototyping is to create screens and reports, thus shaping
most of the proposed system's features in a short period.
Volume and system testing is performed during final system
testing phases. Parallel testing is not needed necessarily,
especially if there's no old system to compare with.
