Union Railway Minister Suresh Prabhakar Prabhu released the book "Indian Railway: The Weaving of a National Tapestry", jointly authored by Sanjay Chadha, Vidya Krishnamurthi and which of the following economists?

Introduction / Context:
"Indian Railway: The Weaving of a National Tapestry" is a book that traces the history and development of Indian Railways. It was released by the Union Railway Minister and is often cited in current affairs and general knowledge questions. This question checks whether you know the full set of authors, focusing on which economist joined Sanjay Chadha and Vidya Krishnamurthi as a co author. The correct answer is Bibek Debroy.

Given Data / Assumptions:

• The title of the book is "Indian Railway: The Weaving of a National Tapestry".
• We are told that Sanjay Chadha and Vidya Krishnamurthi are co authors.
• The options list well known personalities, including economists and administrators.
• We assume the question refers to the original trio of authors.

Concept / Approach:
The concept is familiarity with important books on Indian infrastructure and policy. Bibek Debroy is an economist and policy expert who has worked closely on railway reforms and served on high level committees related to Indian Railways. He co authored this book with Sanjay Chadha and Vidya Krishnamurthi. The strategy is to recall which of the listed names is associated with both economics and Indian Railways literature and then select that person as the missing author.

Step-by-Step Solution:
Step 1: Identify that the book is about Indian Railways, with a historical and policy focus. Step 2: Recall that Bibek Debroy has been a member of NITI Aayog and headed committees on railway restructuring. Step 3: Connect this policy role with his involvement in co authoring a detailed book on Indian Railways. Step 4: Evaluate the other options. Andy Marino is a biographer known for writing about political figures, not for this railway book. Step 5: E. Sreedharan is an engineer and administrator famous as the "Metro Man" of India, but he is not cited as a co author here. Step 6: Rakesh Mohan is an economist who has worked on infrastructure policy, but not as a co author of this specific book. Step 7: C. Rangarajan is a respected economist and former Reserve Bank of India governor, but he is not listed among the authors of this work. Step 8: Only Bibek Debroy fits both the authorship record and the context of Indian Railways policy, so we choose him.

Verification / Alternative Check:
If you look at exam oriented current affairs compilations or news reports from the time of the book's release, they clearly state that "Indian Railway: The Weaving of a National Tapestry" is jointly authored by Bibek Debroy, Sanjay Chadha, and Vidya Krishnamurthi. No such report mentions the other options as co authors. This independent cross check confirms that Bibek Debroy is the correct answer.

Why Other Options Are Wrong:
Andy Marino is associated with political biographies and does not appear in the author list of this railway book. E. Sreedharan is central to Indian metro rail projects, but he did not co write this historical tapestry of Indian Railways. Rakesh Mohan, although an economist, is not recorded as co author of this particular title. C. Rangarajan is known for monetary policy and economic governance, not for this book.

Common Pitfalls:
Students may be tempted to choose any name linked with economics or transport without recalling the exact combination of authors. Another frequent error is to guess E. Sreedharan because his public image is strongly connected with rail systems, even though he did not co author this policy heavy book. Avoid these traps by memorising specific author combinations for prominent government related books mentioned in news and exam material.

Final Answer:
The missing co author of "Indian Railway: The Weaving of a National Tapestry" is Bibek Debroy.
