Name the country

Correct: Tonga. Its flag bears a bold red cross in a white canton on a red field, reflecting the nation’s deep Christian heritage. Adopted in 1875 after King George Tupou I’s conversion, it’s so significant that Tonga’s constitution forbids altering the design. Red symbolizes the blood of Christ; white stands for purity. How to remember: Tonga is a Polynesian kingdom nicknamed the “Friendly Islands”—think of the welcoming Christian cross. Distinguish it from the choices: Tuvalu and Micronesia use light blue with stars, while Papua New Guinea shows a bird-of-paradise and the Southern Cross. Spot the red cross-on-red field, and you’ve found Tonga.
