Which of the following roles would NOT form part of the project team in Requirements...

The Project Sponsor is the senior executive or manager who owns the project, champions it, secures funding, and holds ultimate accountability for the benefits. While they are the most important stakeholder and sign off on the requirements, they are typically NOT an active, day-to-day working member of the project team responsible for executing the Requirements Engineering activities. The Project Manager (A), Business Analyst (C), and Software Tester (D) are all core, active members of the project team with specific roles in managing, defining, and validating the requirements, respectively.
