Who has written the business biography "The Vijay Mallya Story"?

Introduction / Context:
"The Vijay Mallya Story" is a business biography that traces the rise and fall of businessman Vijay Mallya, covering his liquor empire, airline ventures, and legal troubles. The book was written by a journalist who closely studied his career. This question tests whether you know which writer authored this biography rather than assuming that the subject himself wrote it.

Given Data / Assumptions:
• The title of the book is "The Vijay Mallya Story". • Four names are given, including Vijay Mallya and his son along with other individuals. • You have to identify the journalist or author who wrote the biography. • It is assumed that you do not confuse the subject of a biography with its author.

Concept / Approach:
The biography "The Vijay Mallya Story" was written by K. Giriprakash, a journalist who followed Vijay Mallya's business activities and controversies. Many business and banking exams include this question to check candidates' awareness of major Indian corporate biographies. The correct approach is to recall that the author is a reporter and not Mallya himself or his family members.

Step-by-Step Solution:
Step 1: Note that "The Vijay Mallya Story" is clearly presented as a story about Vijay Mallya, implying that it is a biography and not an autobiography. Step 2: Understand that biographies are usually written by journalists or authors other than the subject. Step 3: Recall from business news and book reviews that K. Giriprakash authored this detailed account of Vijay Mallya's business career. Step 4: Locate K. Giriprakash among the options. Step 5: Eliminate Vijay Mallya and Siddharth Mallya, who are the subject and his son, and Gopinath, who is associated with different stories in aviation but not this book. Step 6: Choose K. Giriprakash as the correct answer.

Verification / Alternative check:
Verification can be done by remembering that publishers and media articles specifically credit K. Giriprakash with this biography. The book often appears in lists of business biographies written about Indian corporate figures. Vijay Mallya himself did not release an autobiography with this exact title, and Siddharth Mallya is more associated with entertainment sectors. Gopinath is linked with the low cost airline story of Air Deccan but not with "The Vijay Mallya Story". These checks confirm that K. Giriprakash is the accurate author name to mark.

Why Other Options Are Wrong:
Vijay Mallya is the subject of the biography, not its author. Gopinath is known in connection with the Air Deccan story and entrepreneurship, not as the author of this book. Siddharth Mallya is Vijay Mallya's son and has not written this business biography.

Common Pitfalls:
A typical pitfall is to quickly select Vijay Mallya because his name appears in the book title, without noticing that the question is about the author of a biography. Another mistake is to pick a familiar business name and assume authorship. To avoid these errors, always read whether the book is a biography or an autobiography and remember that journalists often write biographies about business personalities. Keeping a list of major modern Indian biographies and their authors can significantly improve accuracy in such questions.

Final Answer:
The business biography "The Vijay Mallya Story" was written by K. Giriprakash, so K. Giriprakash is the correct option.
