Which of the following describes the Seventh Fleet's Area of Responsibility (AOR)?

• A. Japan, Australia, Philippines, Indonesia
• B. China, Russia, India, NK, ROK
• C. China, Japan, South Korea, Vietnam
• D. India, Pakistan, Bangladesh, Sri Lanka

Answer: (B)

The Seventh Fleet's Area of Responsibility covers the Western Pacific and Indian Ocean, a region where East Asia and South/Southeast Asian waters are central. Describing the AOR with China, Russia, India, North Korea, and South Korea captures the main powers that operate in or around those waters, reflecting the geopolitical landscape the Seventh Fleet focuses on.

Other choices either miss key regional powers or emphasize areas outside the Seventh Fleet’s main focus. For example, leaving out India or Korea, or including nations well outside that core maritime theatre, would not accurately represent the area the Seventh Fleet is assigned to operate in.
