The correct answer is C . PRINCE2 applies management by exception through a hierarchy of delegated authority. The project board establishes the management stage within which the project manager operates, whereas the project manager normally authorizes individual work packages and agrees their requirements and tolerances with the relevant team managers.

The problem in the scenario is therefore not the existence of recycling or sustainability tolerances. Such measurable constraints may legitimately be delegated to a delivery team when they are relevant to its work. The problem is that the project board bypasses the project manager and directly inserts detailed work-package tolerances without those delegated targets being agreed through the normal work-package authorization relationship.

Option A incorrectly creates a direct routine control relationship between the project board and team managers. Option B similarly conflicts with the normal reporting structure: team managers report work-package progress to the project manager, while the project manager provides appropriate progress information to the project board. Option D is incorrect because sustainability performance can be translated into delegated targets and tolerances at lower management levels when appropriate.

The project manager should therefore authorize the relevant work packages, agree achievable delegated tolerances with team managers, and monitor performance against them within the overall stage tolerances authorized by the project board.
