"The crop is subtropical in nature. A hard frost is injurious to it. It requires at least 210 frost-free days and 50 to 100 centimeters of rainfall for its growth. A light well-drained soil capable of retaining moisture is ideally suited for the cultivation of the crop." Which one of the following is that crop?

1. The description outlines specific climatic and soil requirements for a crop. 2. 'Subtropical in nature': Many crops fit this, including Cotton, Sugarcane. 3. 'Hard frost is injurious': This applies to Cotton and Sugarcane. 4. 'Requires at least 210 frost-free days': This is a classic requirement for Cotton cultivation. 5. '50 to 100 centimeters of rainfall': This rainfall range is suitable for Cotton. Sugarcane generally requires more rainfall or irrigation (100-150 cm). Jute requires high rainfall (150-250 cm). Tea also needs high rainfall (150-300 cm) distributed throughout the year. 6. 'Light well-drained soil capable of retaining moisture': This description fits well with the black cotton soils or alluvial soils ideal for Cotton. While Sugarcane can grow on various soils, heavy loams are often preferred. Jute requires alluvial soils. Tea requires well-drained loamy soils, often acidic. 7. Considering all the conditions together, especially the 210 frost-free days and the rainfall range, the description most accurately matches the requirements for Cotton (A).
