Solution
The correct options are
A Rajma
C Peas
Rajma and peas are pulses and called as leguminous crops. The roots of these plants have formed a symbiotic association with certain soil bacteria, called nitrogen fixing. These bacteria fix atmospheric nitrogen into the soil thereby increasing the soil nitrogen content naturally. Thus, these crops should be preferably grown in alternate harvest cycles to replenish the nitrogen content of the soil.
