Which political leader released the book Khushwant Singh: In Wisdom and in Jest about the noted author and journalist?

Introduction / Context:
Khushwant Singh was a very popular Indian author, journalist, and columnist, known for his sharp wit, bold writing style, and commentary on politics, society, and culture. A commemorative book titled "Khushwant Singh: In Wisdom and in Jest" was released to celebrate his life and work. This general knowledge question tests awareness of contemporary Indian public life by asking which political leader released this book at a formal function.

Given Data / Assumptions:

• The book is titled "Khushwant Singh: In Wisdom and in Jest".
• It is a work related to the life, writings, and humour of Khushwant Singh.
• The options list four well known Indian political leaders: Yogi Adityanath, Vijay Rupani, Shivraj Singh Chouhan, and Amarinder Singh.
• The task is to identify which leader released the book at an official event.

Concept / Approach:
This is a fact based static general knowledge question, not a conceptual or numerical problem. The approach is to recall the correct association between the book and the leader who released it. Often, such questions are framed from news events where a book launch is presided over by a chief minister or a prominent political figure related to the state or region of the subject. Since Khushwant Singh had a strong connection with Punjab, the launch of the book is logically linked with a leader from Punjab.

Step-by-Step Solution:
Step 1: Identify the book mentioned in the question, "Khushwant Singh: In Wisdom and in Jest", as a tribute volume about writer and journalist Khushwant Singh. Step 2: Recall that this book was released at a formal event by a chief minister closely associated with the state of Punjab, where Khushwant Singh had deep roots and public recognition. Step 3: Examine the options. Yogi Adityanath is associated with Uttar Pradesh, Vijay Rupani with Gujarat, Shivraj Singh Chouhan with Madhya Pradesh, and Amarinder Singh with Punjab. Step 4: Link the book to Punjab based public events and remember that Captain Amarinder Singh, then Chief Minister of Punjab, released this book. Step 5: Therefore, the correct answer is Amarinder Singh.

Verification / Alternative check:
One way to verify this logically is to consider the probability that a tribute to Khushwant Singh would be released in a context that honours his connection with Punjab. Among the given leaders, Amarinder Singh stands out as the one directly associated with Punjab as chief minister. A second check is to recall that national and regional media carried images and reports mentioning Amarinder Singh releasing this book. No such association is commonly reported with the other three leaders in the context of this particular title.

Why Other Options Are Wrong:
Yogi Adityanath: He is known as the chief minister of Uttar Pradesh and there is no widely known link between him and the launch of this specific book on Khushwant Singh.
Vijay Rupani: He served as chief minister of Gujarat, and there is no major public record of his involvement in releasing "Khushwant Singh: In Wisdom and in Jest".
Shivraj Singh Chouhan: He is associated with Madhya Pradesh politics, not with Punjab based literary events concerning Khushwant Singh.

Common Pitfalls:
A common mistake is guessing based only on name familiarity rather than remembering the regional or contextual connection between the leader and the literary figure. Another pitfall is to assume that any well known chief minister might be correct without considering Khushwant Singh's strong link to Punjab. Students may also confuse this book with other tribute volumes released by different leaders at different times and select an option based solely on prominence in recent news instead of the specific event.

Final Answer:
The political leader who released the book "Khushwant Singh: In Wisdom and in Jest" is Amarinder Singh.
