The autobiography "The Race of My Life" was co authored by Milkha Singh and his daughter. What is the name of his daughter who co authored this book?

Introduction / Context:
"The Race of My Life" is the autobiography of legendary Indian sprinter Milkha Singh. It gives a detailed account of his struggles, achievements, and personal life. The book was co authored with his daughter, and many exams ask about her name to test both knowledge of sports personalities and awareness of their literary contributions. This question combines sports general knowledge with books and authors.

Given Data / Assumptions:
• The title of the autobiography is given as "The Race of My Life". • It is stated that the book was co authored by Milkha Singh and his daughter. • Four possible names are provided as options for the daughter. • You only need to remember or recognise the correct name, not other details of the book.

Concept / Approach:
The important concept is that Milkha Singh collaborated with his daughter Sonia Sanwalka to write "The Race of My Life". The approach is to recall that Sanwalka is the surname of his daughter and that the book credits both names as co authors. Exam questions often use this detail to differentiate students who have carefully studied sports biographies and current affairs from those who only know the athlete's name.

Step-by-Step Solution:
Step 1: Recognise that "The Race of My Life" refers to the life story of Milkha Singh, a legendary Indian sprinter. Step 2: Recall that the book was written jointly by Milkha Singh and his daughter. Step 3: Among the options, identify names that could realistically belong to his daughter. Step 4: Remember that the co author's full name is Sonia Sanwalka, which is explicitly mentioned in many articles about the book. Step 5: Select Sonia Sanwalka as the correct answer.

Verification / Alternative check:
Verification can be achieved by recalling promotions, interviews, or book reviews that mention "The Race of My Life" as being written by Milkha Singh with his daughter Sonia Sanwalka. Other sources such as library catalogues and publishing information also credit both names. None of the other names in the options are reported in connection with this autobiography, which confirms that Sonia Sanwalka is the correct co author.

Why Other Options Are Wrong:
Mankhia Singh is not known as the co author of this autobiography. Sanjitia Sardar is not associated with the writing of "The Race of My Life". Poonam Dillo sounds like the name of an actress but is not linked to this book as co author.

Common Pitfalls:
Students may mistakenly assume that the co author must share the same surname Singh or may guess randomly among unfamiliar names. Another pitfall is ignoring details of sports biographies, concentrating only on match statistics rather than the off field contributions of athletes. To avoid these mistakes, it is helpful to pay attention when reading about autobiographies and to note the co authors, especially when they are close family members. Creating simple flashcards that link each famous sportsperson with their major book is also a good revision strategy.

Final Answer:
The daughter of Milkha Singh who co authored the autobiography "The Race of My Life" is Sonia Sanwalka, so that is the correct option.
