• The question asks which country Wang Yihan represents.
• Options are Indonesia, Taiwan, China and Japan.

Concept / Approach:
Wang Yihan is a former world champion and one of the top women singles shuttlers from China. She has been part of the dominant Chinese badminton setup for many years. The approach is to recall her as a Chinese player and distinguish her from major Indonesian, Taiwanese and Japanese opponents who have different names.

Step-by-Step Solution:
Step 1: Recall top women singles players around the time of the Rio 2016 Olympics and match them with their countries.Step 2: Recognise that Wang Yihan is a leading player from China and has won world level titles representing that country.Step 3: Indonesia, Taiwan and Japan also have strong badminton programmes, but their famous players in this period include different names such as Saina Nehwal opponents or local stars.Step 4: During Sindhu run at Rio, her quarterfinal victory over Wang Yihan was often described as India beating a Chinese champion.Step 5: Therefore the correct option for Wang Yihan country is China.

Verification / Alternative check:

Wang Yihan played for the Chinese national team in many Uber Cup and World Championship events. She has never represented Indonesia, Taiwan or Japan. This consistent association with China confirms the answer.

Why Other Options Are Wrong:
Option A, Indonesia, is wrong because Indonesian women singles players have different names, and Wang Yihan is not among them. Option B, Taiwan, and option D, Japan, are also incorrect since they have their own star shuttlers who are distinct from Wang Yihan. These countries are strong in badminton, but their inclusion here is only to test whether the candidate can correctly link name and nationality.

Common Pitfalls:
A common mistake is to confuse Chinese and other East Asian or Southeast Asian players because of similar sounding names or because they often meet in later stages of tournaments. Another pitfall is simply guessing based on which country is currently strongest in badminton. To avoid this, make a habit of linking prominent players like Wang Yihan directly with their national teams when revising tournament results.

Final Answer:
Wang Yihan represents China in international badminton.
