The correct answer is D . A product description must define a product sufficiently clearly for its creation, review, and approval to be planned and controlled. Merely stating that the shopping centre will contain an underground car park identifies the existence of a required component, but it does not provide an adequate quality specification .

For effective quality management, measurable characteristics should be established so that the product can be objectively assessed against agreed expectations. Depending on the product, these may include capacity, dimensions, accessibility provisions, charging facilities, structural requirements, security arrangements, environmental standards, or other measurable characteristics. Appropriate quality tolerances may also be defined where controlled variation is permissible.

Option A is incorrect because existence alone does not establish whether the car park is fit for purpose. Option B similarly confuses confirmation of delivery with verification of acceptable quality. Option C is incorrect because the quality management approach defines how quality will be managed across the project; it is not the repository for all detailed product-specific quality specifications.

The product description therefore needs sufficient measurable information to enable planning of quality-control activities and objective verification that the delivered product meets its defined requirements.
