Who is the author of the Bengali short story collection "Panchashati Galpo"?

Introduction / Context:
"Panchashati Galpo" is an acclaimed Bengali collection of short stories, and questions about its authorship often appear in competitive exams under the books and authors category. The correct author is Atin Bandyopadhyay, a noted Bengali writer. This question checks whether you can distinguish his work from those of other prominent Bengali authors listed in the options.

Given Data / Assumptions:

• The book title is "Panchashati Galpo".
• The options include several Bengali writers known for fiction and short stories.
• The question focuses on the original author of this particular collection.
• Only one of these writers has actually been credited with "Panchashati Galpo".

Concept / Approach:
The concept tested here is the mapping between regional language works and their authors. Atin Bandyopadhyay received recognition, including the Sahitya Akademi Award, for "Panchashati Galpo". The approach is to recall this specific link and avoid confusing it with other Bengali writers who have different notable works. A good memory for such associations is especially important because many names may look familiar to candidates but belong to different titles.

Step-by-Step Solution:
Step 1: Identify that "Panchashati Galpo" is a Bengali short story collection. Step 2: Recall that Atin Bandyopadhyay gained major recognition for this very work and was honoured for his contribution to Bengali literature. Step 3: Consider Samaresh Basu, who wrote other significant novels and stories but not this particular collection. Step 4: Consider Moti Nandi, noted for sports themed stories and children's literature, not for "Panchashati Galpo". Step 5: Consider Buddhadeb Guha, a popular novelist known for different works, especially in the adventure and romantic genre. Step 6: Consider Sunil Gangopadhyay, a celebrated writer and poet with famous titles of his own, but again not associated with this book. Step 7: Since only Atin Bandyopadhyay is directly linked with "Panchashati Galpo", we select him as the correct answer.

Verification / Alternative Check:
Reference books on Bengali literature and general knowledge compilations consistently state "Panchashati Galpo – Atin Bandyopadhyay". He is also mentioned in news reports and literary notes as the author honoured for this collection. No reliable source attributes the book to any of the other options, confirming that the correct author is Atin Bandyopadhyay.

Why Other Options Are Wrong:
Samaresh Basu is an important Bengali writer, but his notable works have different titles and themes. Moti Nandi focused on other story collections and novels, particularly in sports and youth fiction, not this one. Buddhadeb Guha is known for adventure, travel, and romantic fiction in Bengali, not "Panchashati Galpo". Sunil Gangopadhyay wrote many influential works but is not associated with this specific short story compilation.

Common Pitfalls:
The major pitfall is that candidates may simply pick any familiar Bengali name without recalling the exact match with the book title. Since all the options are respected authors, this strategy leads to random guessing. To avoid such errors, aspirants should memorise clear pairs of regional books and authors, especially those frequently mentioned in awards and exam oriented notes.

Final Answer:
The book "Panchashati Galpo" was written by Atin Bandyopadhyay.
