Which flag features a red circle on a white background?

• A. China
• B. Indonesia
• C. South Korea
• D. Japan

Answer: (D)

Recognizing flags by their most recognizable symbol helps. The flag with a single red circle centered on a white field is Japan’s; the red disc represents the sun. This distinguishes it from the flag of China, which has a red field with five yellow stars; Indonesia, which is red over white in two horizontal bands; and South Korea, which features a red and blue yin-yang symbol surrounded by black trigrams. So the red circle on white uniquely identifies Japan.
