Step 1: Read the conditions in the flow chart. The chart points to heavy rainfall combined with high temperature and strong leaching of the soil. Step 2: Link these conditions to a soil type. Heavy leaching washes away silica and soluble minerals, leaving behind iron and aluminium oxides, which gives the soil a reddish colour, and this is exactly how laterite soil forms. Step 3: Recall where this soil is found. Such soil occurs in high rainfall areas like the Western and Eastern Ghats, Kerala, Karnataka and parts of Assam, and works well for plantation crops like tea and coffee once fertilised. Step 4: Answer. The missing soil in the chart is laterite soil, option B.
