The correct answer is C.
OBJ-2.1: The purpose of tailoring is to ensure that project controls are appropriate to the project’s scale, complexity, importance, team capability and risk (e.g. the frequency and formality of reports and reviews). Tailoring requires the project board and the project manager to make proactive choices and decisions on how PRINCE2 will be applied. When tailoring PRINCE2, it is important to remember that effective project management requires information (not necessarily documents) and decisions (not necessarily meetings).
