Which term is the approval of a design that is required to be given by the competent authority of the state of origin of the design?

• A. Containment System
• B. Confinement System
• C. Multilateral Approval
• D. Unilateral Approval

Answer: (D)

Unilateral approval. The design is approved by the competent authority of the state of origin, meaning one country’s regulator grants the approval based on its own standards and regulations. This single-jurisdiction decision is what defines unilateral approval, as opposed to processes that require joint action or recognition by multiple states. The other terms don’t describe this process: containment and confinement relate to safety features within a design, not who approves it; multilateral approval would involve several states agreeing, whereas unilateral is specifically a single-state decision.
