A the Philippines
B Chile
C Republic of Korea

AI Explanation

The correct answer is D) Australia. The IALA-A Buoyage System is used to mark channels and waterways in countries that are members of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) Region A, which includes Australia and other countries in the Eastern Hemisphere. The other answer choices (the Philippines, Chile, and the Republic of Korea) are located in regions that use different buoyage systems, such as IALA-B or other national systems, and would not be expected to have channels marked with the IALA-A system.
