“The crop is subtropical in nature, A hard frost in injurious to it. It requires at least 210 frost-free days and 50 to 100 centimetres 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?

The description provided matches the requirements for cotton cultivation. - Subtropical nature and frost sensitivity: Cotton is a subtropical crop and is sensitive to frost. A hard frost can damage the cotton plants, making them unsuitable for cold regions.
- Frost-free days: Cotton requires at least 210 frost-free days, which is typical for its growth cycle. It thrives in regions with a long growing season, free from frost.
- Rainfall requirement: Cotton needs 50 to 100 cm of rainfall. The crop is drought-tolerant, but it still requires moderate rainfall for optimal growth.
- Soil type: Cotton grows best in light, well-drained soil that can retain moisture, providing the right balance for its deep root system. Cotton is the right answer. Hence, option A is the correct answer.
