Answer: (B)
Cotton requires black soil, light rainfall, high temperature, and bright sunshine — these are the ideal geographical conditions for its cultivation.
Cotton is a Kharif crop grown in black (regur) soil, which retains moisture well. It needs high temperature (21–30°C), low to moderate rainfall, and plenty of bright sunshine for the bolls to open. Laterite soil and high/low rainfall are unsuitable for cotton. Examiners expect students to recall the specific soil type and climatic needs of cotton directly from the cropping pattern section.
