Mustard
Explanation
Crops are classified based on their economic utility and the specific plant part consumed. Oilseed crops are cultivated primarily to extract vegetable oil from their seeds, which serves as a major source of dietary fat and energy.Option Analysis:
- Spinach: This is a leafy vegetable crop cultivated for its edible leaves, which are rich in vitamins and minerals. It is not cultivated for oil production.
- Mustard: This is a major oilseed crop. Its seeds contain a high percentage of oil (approximately 30–48%). The seeds are processed to extract edible mustard oil, which is widely used for cooking.
- Banana: This is a fruit crop cultivated for its fleshy fruit, which is a source of carbohydrates. Commercial banana varieties are typically parthenocarpic (seedless) and are not sources of oil.
- Carrot: This is a root vegetable cultivated for its modified taproot, which stores food. While carrot seeds exist for propagation, the crop is not cultivated as a source of edible oil.
Key Takeaway: Mustard is an oilseed crop cultivated for the oil stored in its seeds, distinct from crops cultivated for leaves (spinach), fruits (banana), or roots (carrot).
