Step 1: Understanding the Concept:
The question names a specific piece of writing, "Hunger and Entitlements," and asks which of four well known Indian writers produced it.
Step 2: Key Formula or Approach:
Match the subject of the title to the field each option is known for. A title about hunger and entitlements points to an economist studying famine, not a novelist.
Step 3: Detailed Explanation:
Amartya Sen built his reputation on showing that famines are usually caused by a collapse in people's ability to command food, what he called their "entitlement," rather than by there being too little food in a country overall. He used this idea to explain famines such as the Bengal famine of 1943, where food was available but many people had lost the income or rights needed to obtain it.
"Hunger and Entitlements" is one of the works where Sen set out this argument, and it fits directly with the Nobel Prize winning research that made him famous.
Khushwant Singh wrote about partition and Sikh history, Kiran Desai wrote prize winning fiction, and Arundhati Roy is known for fiction and political essays. None of them worked on famine economics.
Step 4: Final Answer:
The author of "Hunger and Entitlements" is Amartya Sen, the economist known for the entitlement theory of famine.
