In which city did Yuvraj Singh make his One Day International (ODI) debut for India?

Introduction / Context:
Debut venues of famous cricketers are common questions in sports general knowledge. Yuvraj Singh is one of India most celebrated limited overs cricketers. This question asks you to recall the city where he played his first One Day International for India.

Given Data / Assumptions:

• The player is Yuvraj Singh.
• The format is One Day International (ODI) cricket.
• We must select the debut city from Nairobi, Mumbai, London and Lahore.
• We assume the question refers to his actual first ODI appearance for India.

Concept / Approach:
Yuvraj Singh made his ODI debut for India during the ICC KnockOut tournament (later known as the Champions Trophy), which was held in Nairobi, Kenya. Remembering this link between his early career and the Nairobi venue is the essential concept behind answering this question.

Step-by-Step Solution:
Step 1: Recall that Yuvraj Singh first came to international prominence in a multi nation ICC tournament in Kenya. Step 2: Connect this memory with the ICC KnockOut event played in Nairobi. Step 3: Check the four options and look for the Kenyan city. Step 4: Identify Nairobi, Kenya as the location that matches your recollection. Step 5: Select Nairobi, Kenya as the correct answer.

Verification / Alternative check:
You can verify this information by checking Yuvraj Singh career statistics on any major cricket database. It will list his ODI debut as being against Kenya or another team in the ICC KnockOut event hosted in Nairobi. This confirms the city and removes confusion with Indian or English venues.

Why Other Options Are Wrong:
Mumbai, India: Yuvraj later played many matches in India, but his ODI debut did not occur in Mumbai.
London, England: London is a major cricket venue but is not the city where he debuted for India in ODIs.
Lahore, Pakistan: India has toured Pakistan, yet Yuvraj debut took place earlier in a neutral venue tournament hosted in Kenya.

Common Pitfalls:
Students sometimes assume that all famous Indian players debut at home grounds like Mumbai or other major Indian cities. Another pitfall is forgetting that some players debut in multi nation tournaments played at neutral venues. To avoid such mistakes, it helps to memorise a few iconic debut stories, such as Yuvraj Singh breakthrough in Nairobi.

Final Answer:
Yuvraj Singh made his ODI debut for India in the city of Nairobi, Kenya.
