Which term means the body or authority designated or recognized for any purpose in connection with these regulations?

• A. Multilateral Approval
• B. Competent Authority
• C. Unilateral Approval
• D. Transport Index

Answer: (B)

The concept being tested is identifying the official body designated or recognized to act under these regulations. The term that fits this is competent authority, which refers to the government body empowered to enforce and oversee compliance with the regulations. This authority issues approvals, certifications, and inspections, and serves as the recognized contact point for implementing the rules. For example, a national aviation authority acts as the competent authority, ensuring safety and regulatory compliance across carriers and operations. The other terms don’t describe a governing body: multilateral approval implies consent from many parties, unilateral approval is from a single party, and the Transport Index is a radiation-safety measurement on packaging, not a regulatory authority.
