Explanation: The Harappan civilization, also known as the Indus Valley Civilization, was a sophisticated urban society that thrived in the northwestern regions of the Indian subcontinent from around 3300 BCE to 1300 BCE. Agriculture was a fundamental aspect of the Harappan economy, providing sustenance for the large urban populations and supporting the development of a complex society.
The Harappans cultivated a variety of crops, which included cotton, wheat, and peas. Each of these crops played a significant role in the agricultural and economic life of the civilization.
1. **Cotton**: Cotton was one of the most important crops for the Harappans. It was not only a food source but also a crucial raw material for textile production. The Harappans were skilled in weaving and dyeing cotton fabrics, which were used for clothing and for trade. The presence of cotton seeds and textiles in archaeological sites provides evidence of its cultivation and importance.
2. **Wheat**: Wheat was a staple crop in the Harappan diet. It was a reliable source of carbohydrates and was used to make bread and other food items. Archaeological findings, including charred grains and storage facilities, indicate that wheat was widely cultivated and stored for consumption and trade.
3. **Peas**: Peas were another crop that the Harappans cultivated. They were a source of protein and were likely used in various dishes to supplement the diet. The cultivation of peas, along with other legumes, helped to enrich the soil and provided a balanced diet for the population.
The cultivation of these crops reflects the agricultural diversity and sophistication of the Harappan civilization. The Harappans had developed advanced agricultural techniques, including irrigation systems, to support the cultivation of these crops. The variety of crops also indicates a well-rounded diet and a resilient agricultural system that could withstand fluctuations in climate and soil conditions.
In conclusion, the Harappans cultivated a diverse range of crops, including cotton, wheat, and peas, which were essential for their economy and sustenance. This agricultural diversity was a key factor in the success and longevity of the Harappan civilization. Therefore, the correct answer is (D) All of these, as all the mentioned crops were indeed cultivated by the Harappans.
