Which one among the following agricultural crops/ groups of crops may be grown in abundant in lowlands and river deltas of fertile alluvial soil where there is high summer temperature and rainfall varies from 180 cm to 250 cm?

The specified conditions of lowlands, river deltas, and fertile alluvial soil combined with high summer temperatures and high rainfall (180–250 cm) are ideal for rice and jute. Rice thrives in high temperatures (above 25°C) and high rainfall (above 100 cm) in water-retaining alluvial clayey soils. Jute specifically requires warm, humid conditions (24–35°C) and high rainfall (150–250 cm), typically found in the floodplains and deltas of West Bengal and Bangladesh [1]. Tea, while requiring well-drained slopes to avoid stagnant water, is a major crop in the high-rainfall wet belt (100–250 cm) of Northeast India alongside rice and jute [1]. In contrast, wheat and maize require moderate rainfall (50–100 cm), and cotton prefers lower rainfall (50–100 cm) and black soil, making them unsuitable for the described high-moisture deltaic environment.
