Krishna Sobti received the 53rd Jnanpith Award. Which of the following books was not written by her?

Introduction / Context:
The Jnanpith Award is one of the highest literary honours in India, given for outstanding contributions to literature in any Indian language. Hindi writer Krishna Sobti received the 53rd Jnanpith Award. This question checks both your knowledge of her major works and your ability to distinguish them from a title that does not belong to her bibliography.

Given Data / Assumptions:

The author in focus is Krishna Sobti, a celebrated Hindi novelist.
She is the recipient of the 53rd Jnanpith Award.
Three of the options correspond to her famous works.
One option is a book that is not written by her.

Concept / Approach:
To answer this, you must know or recall which titles are associated with Krishna Sobti. Her major novels include Daar Se Bichhudi, Mitro Marjani and Zindaginama, among others. The title Vishw Mithok Sarit Sagar does not belong to her body of work and is included as a distractor. By matching each option with known works of Krishna Sobti, you can identify which one is not hers.

Step-by-Step Solution:
Step 1: Recognise that the question links Krishna Sobti to the 53rd Jnanpith Award and is asking you to identify a book that she did not write. Step 2: Recall some of her famous works. These include Daar Se Bichhudi, Mitro Marjani and Zindaginama, all of which are strongly associated with her name in Hindi literature. Step 3: Examine the options and match them with her known works. Daar Se Bichhudi appears, as does Mitro Marjani and Zindaginama. Step 4: Note that Vishw Mithok Sarit Sagar does not feature among commonly listed works of Krishna Sobti and is not recognised as one of her novels. Step 5: Conclude that Vishw Mithok Sarit Sagar is the title that was not written by Krishna Sobti.

Verification / Alternative check:
As a verification method, think of short descriptions of her well known novels. Zindaginama is often described as a monumental novel about rural life and history, Mitro Marjani is known for its bold portrayal of a woman character, and Daar Se Bichhudi is cited as another important work. These titles consistently appear in discussions of Krishna Sobti's writing. In contrast, scholarly articles and reference lists that detail her bibliography do not mention a work called Vishw Mithok Sarit Sagar, which suggests that this title is not associated with her authorship. This confirms that it is the correct choice for the book not written by her.

Why Other Options Are Wrong:
Daar Se Bichhudi: This is a known work by Krishna Sobti and is frequently cited in discussions of her literature, so it is not the correct answer to this question.
Mitro Marjani: Another famous novel by Krishna Sobti, recognised for its strong female character and innovative style, so it cannot be considered a book not written by her.
Zindaginama: Often described as one of her most significant and expansive works, it played a role in her receiving the Jnanpith Award, so this option is definitely not the odd one out.

Common Pitfalls:
A common pitfall is to assume that the longest or most complex title is the one that must belong to the author being discussed. Alternatively, students sometimes guess randomly when they see unfamiliar titles. To avoid this, it is helpful to remember at least two or three major works of each important author. In the case of Krishna Sobti, remembering the trio of Zindaginama, Mitro Marjani and Daar Se Bichhudi is enough to recognise that the remaining unfamiliar title does not belong to her.

Final Answer:
The book that was not written by Krishna Sobti is Vishw Mithok Sarit Sagar.
