Question

reason and assertion (A -Legumes revive the soil fertility.
R-Legumes are the rich source of proteins.]
​

Answer 1

Answer:

both reason and assertion are true and R explains  A

Explanation:

Legumes are plants that bear their seeds in pods. They differ markedly from grasses, cereals and other non-legume crops because much of the nitrogen they require is produced through fixation of atmospheric nitrogen by bacteria in nodules on their roots. As a result, legumes are rich in protein.
