Which among the following country and popular sport pairs is NOT incorrectly matched, so that there is no mismatched pair in the list?

Introduction / Context:
This question is framed in a slightly tricky way around country and popular sport associations. Many exams ask about national games or sports strongly associated with particular countries. Here, instead of asking which pair is correctly matched, the question uses the phrase not correctly matched and then offers None of the above as an option. Understanding that all listed pairs are in fact commonly associated helps you realise that there is actually no mismatched pair, so None of the above becomes the correct choice.

Given Data / Assumptions:
- Three specific country and sport pairs are given: Pakistan with Field Hockey, China with Table Tennis, and the United States with Baseball.
- The fourth option is None of the above, which implies that all listed pairs may be correct, leaving no incorrectly matched pair.
- The question uses the phrase not correctly matched, so we must be careful with the double negative logic.

Concept / Approach:
The concept here is general sports awareness. Pakistan has a very strong tradition in field hockey, China is dominant in table tennis, and baseball is widely associated with the United States. The approach is to check each pair and decide whether any pair is clearly wrong. If all pairs are consistent with common general knowledge, then there is no incorrectly matched pair and the correct answer becomes None of the above. The slightly confusing wording is meant to test your careful reading, not just memory.

Step-by-Step Solution:
Step 1: Evaluate Pakistan - Field Hockey. Pakistan has been historically strong in international field hockey and this sport is widely regarded as a traditional national game, so this pair is acceptable. Step 2: Evaluate China - Table Tennis. China dominates world table tennis with repeated Olympic and world titles, so this association is also clearly correct. Step 3: Evaluate USA - Baseball. Baseball is one of the most popular sports in the United States, with Major League Baseball as a major professional league. The pair is therefore appropriate. Step 4: Since all three given pairs are consistent with widely known sports associations, none of them can be called incorrectly matched. Step 5: When no pair is incorrect, the answer that best fits the question is None of the above.

Verification / Alternative check:
You can validate these associations by recalling international sports events and media coverage. Pakistan is remembered for its hockey world cup and Olympic achievements. China is almost always dominant in table tennis at the Olympic Games and world championships. In the United States, baseball is part of the cultural identity, often called the national pastime. Since all three pairs match these well known facts, it confirms that the question contains no wrong pair, so None of the above must be selected.

Why Other Options Are Wrong:
Pakistan - Field Hockey: This is a correct association, not a wrong one. Selecting it would contradict factual sports history, so it is not the answer to a question about incorrectly matched pairs.
China - Table Tennis: China is correctly paired with table tennis, so it cannot be the incorrect pair the question is looking for.
USA - Baseball: Baseball is correctly associated with the United States as a major national sport, so this option is also not incorrect.

Common Pitfalls:
The main pitfall is misreading the wording and getting confused by the negative phrase not correctly matched. Some candidates also mistakenly believe that only officially declared national games matter, whereas this type of question often uses popular associations. Others tend to ignore None of the above because it feels like a trick. The safe strategy is to carefully check each pair and only choose a specific pair if it is clearly wrong. If none is wrong, then None of the above is logically correct.

Final Answer:
There is no mismatched pair in the list, so the correct option is None of the above.
