The correct answer is: A. Saffron.
Saffron is a spice derived from the dried stigmas of Crocus sativus, commonly known as the saffron crocus. It is one of the most expensive spices by weight, and is valued for its rich color and flavor. Saffron is native to Iran, but is also cultivated in Greece, Spain, Italy, Morocco, and India.
Pulwama district is located in the Indian state of Jammu and Kashmir. It is the largest district in the state by area, and is home to a population of over 1.2 million people. The district is known for its production of saffron, which is grown in the foothills of the Himalayas. Saffron is the main source of income for many people in the district, and is a major contributor to the local economy.

- Apples are not a major agricultural product in Pulwama district.
- Rice is grown in the district, but it is not as important as saffron.
