Vijay Singh is indeed from Fiji, which is confirmed by the correct answer option 1. Singh was born in Lautoka, Fiji, and grew up in Nadi. He is a world-renowned professional golfer who has won major tournaments throughout his career.

Option 2, Mauritius, is not correct because although Mauritius is an island nation like Fiji, they are geographically distinct. Mauritius is located in the Indian Ocean off the southeast coast of Africa, while Fiji is in the South Pacific Ocean.

Option 3, Malaysia, is also incorrect. Malaysia is located in Southeast Asia and is known for its busy cities, lush landscapes, and beautiful coastlines. Though it has produced notable athletes, Vijay Singh is not one of them.

Option 4, Kenya, is not the correct answer either. Kenya is a country in East Africa, famous for its diverse wildlife and rich cultural heritage. It`s internationally renowned for its athletics competence, particularly in long-distance running, but not golf.
