In modern Indian writing for young readers, who is the author of the book titled "The Gita for Children"?

Introduction / Context:
"The Gita for Children" is a popular contemporary retelling of the Bhagavad Gita written in a friendly style aimed at young readers and families. This question checks awareness of important modern Indian authors who reinterpret classical texts for children. Such books bridge traditional philosophy and present day language, so they regularly appear in general knowledge sections about literature, education and culture. Recognizing Roopa Pai as the author shows familiarity with current Indian children's writing.

Given Data / Assumptions:

• The title of the book is "The Gita for Children".
• The book is clearly intended to introduce the Bhagavad Gita to younger audiences.
• Four author names are given: Puja Changoiwala, Ruchira Gupta, Priyanka Mookerjee and Roopa Pai.
• We assume the question refers to the well known English language book widely sold in India.

Concept / Approach:
The correct approach is to connect each author with the genre they are known for. Roopa Pai is a Bengaluru based author known for writing engaging non fiction and mythological retellings for children, including "The Gita for Children". The other named writers are associated with very different subject areas such as crime reporting, social activism or literary work that does not focus on child friendly religious retellings. When the title explicitly mentions the Gita and children together, it strongly indicates Roopa Pai, whose work has become a standard reference for parents and schools.

Step-by-Step Solution:
Step 1: Notice that the book introduces the Gita specifically to children, combining a spiritual classic with accessible storytelling. Step 2: Recall that Roopa Pai has written several books that reinterpret Indian philosophy and history in a way that appeals to young readers. "The Gita for Children" is one of her most famous titles. Step 3: Compare with Puja Changoiwala, who is better known for crime and non fiction narratives, not for child oriented religious texts. Step 4: Consider Ruchira Gupta and Priyanka Mookerjee, who are not widely recognized as authors of this particular book and are not strongly associated with the Gita for children genre. Step 5: From these associations, identify Roopa Pai as the only credible author of "The Gita for Children".

Verification / Alternative check:
You can verify through memory of book covers seen in bookstores or online platforms where her name appears prominently on "The Gita for Children". Many school reading lists and parent recommendations mention Roopa Pai by name. Another mental check is to recall related titles like "The Vedas and Upanishads for Children" which are similarly structured and also written by her. These reinforcing connections confirm that option D is the correct choice and reduce the chance of mixing up less relevant names from the options.

Why Other Options Are Wrong:
Puja Changoiwala is recognized as a journalist and author in true crime and social issues rather than mythological retellings for youngsters, so option A is incorrect for this title. Ruchira Gupta is known primarily as a social activist and writer in the field of human trafficking and women's rights, and she did not author this children's Gita book, so option B is wrong. Priyanka Mookerjee is not associated with this specific work either, which makes option C incorrect. Only Roopa Pai clearly matches the title and readership of "The Gita for Children".

Common Pitfalls:
One common pitfall is to treat all Indian female authors in the options as equally likely and to guess randomly, especially if the candidate has heard some of the names in the news. Another mistake is to confuse "The Gita for Children" with other Gita translations or commentaries intended for adults, which are written by different scholars. To avoid such confusion, it is helpful to build specific associations: Roopa Pai for child focused Indian non fiction and mythology, and other authors for their distinct domains. This habit strengthens long term recall for similar general knowledge questions.

Final Answer:
Roopa Pai
