The flag of which Asian nation features a red circle on a white background?

• A. China
• B. Japan
• C. Vietnam
• D. Indonesia

Answer: (B)

The design being tested is recognizing a national flag by its emblem and colors. A red circle centered on a white field is Japan’s flag, often called Hinomaru. The red circle represents the sun, a prominent symbol in Japanese culture and the idea of the country as the “land of the rising sun.” The white background emphasizes purity and sincerity while showcasing the sun disc clearly.

Among the options, the other flags have different designs: China uses a red field with yellow stars, Vietnam uses a red field with a yellow star, and Indonesia uses two horizontal bands of red over white. None of those feature a red circle on white, so Japan is the correct flag.
