In the twenty second Asian Athletics Championship AAC held in 2017 which Indian athlete carried the national flag and served as the flag bearer for the Indian contingent during the opening ceremony

Introduction / Context:
Major international sports events often begin with an opening ceremony during which each country contingent marches with its national flag. The athlete chosen as flag bearer generally has a strong record or symbolic significance. The twenty second Asian Athletics Championship AAC in 2017 was an important continental event hosted by India and this question asks you to recall the Indian athlete who led the team as flag bearer.

Given Data / Assumptions:

• The event is the twenty second Asian Athletics Championship 2017.
• The question is about the Indian contingent.
• Four well known Indian sportspersons are provided as options.
• We assume familiarity with Indian athletics and Olympic sports news around 2017.

Concept / Approach:
To answer the question you should connect the specific competition with athletes who specialise in athletics rather than shooting or gymnastics. From there you can narrow down which athlete was actively competing at that championship and selected to carry the flag. This mix of elimination and recall helps identify the correct option efficiently.

Step-by-Step Solution:
Step 1: Note that the event is an athletics championship so the flag bearer is likely to be an athletics star. Step 2: Among the options Jitu Rai is a shooter and Dipa Karmakar is a gymnast so they are less likely in this context. Step 3: The remaining options Srabani Nanda and Tintu Luka are track athletes. Step 4: News reports from the 2017 Asian Athletics Championship held in Bhubaneswar mentioned that middle distance runner Tintu Luka was chosen as the flag bearer for the Indian team. Step 5: Therefore Tintu Luka is the correct answer.

Verification / Alternative check:
An alternative verification is to recall that Tintu Luka had previously represented India in international competitions in events such as the eight hundred metre race and was one of the senior athletes in the national squad at that time. Being a senior and accomplished athlete makes her a natural choice for leading the contingent which supports the conclusion that she served as flag bearer.

Why Other Options Are Wrong:
Srabani Nanda is a sprinter but she was not reported as the flag bearer for this specific championship. Jitu Rai is associated with shooting events not athletics and therefore would not lead a purely athletics contingent. Dipa Karmakar is a gymnast known for artistic gymnastics events such as vault and is unrelated to the Asian Athletics Championship march past.

Common Pitfalls:
Many candidates pick a very famous athlete like Dipa Karmakar due to name recognition without considering whether the sport matches the event. Another mistake is not distinguishing between multi sport events such as the Olympics and single sport championships such as athletics meets. Always check the sport mentioned in the question to avoid such confusion.

Final Answer:
The flag bearer for the Indian contingent at the twenty second Asian Athletics Championship 2017 was Tintu Luka.
