Your answer: —  Â·  Correct: D
Explanation

Cotton is a tropical and sub-tropical crop that requires specific climatic conditions for successful cultivation. It thrives in warm climates with temperatures typically ranging between 21°C and 30°C [2]. It requires moderate to light rainfall, generally between 50 cm and 100 cm, or irrigation in drier regions [3]. Soil requirements include well-drained medium loam or the moisture-retentive black cotton soil of the Deccan Plateau [4]. However, the most critical requirement is a long frost-free period. While the question suggests 100 days, standard geographical requirements for cotton maturation are significantly higher, typically requiring at least 180 to 210 frost-free days [2]. A period of only 100 days is insufficient for the crop to mature, as it usually takes 6 to 8 months to reach harvest [2]. Therefore, option 4 is the incorrect geographical requirement.
