▶ Answer & Explanation

Correct answer: A. 1, 3 and 4 only

Nitrogen-fixing plants are crucial for enriching soil fertility. Legumes, such as Alfalfa (Lucerne), Chickpea, and Clover, are well-known for their ability to fix atmospheric nitrogen through a symbiotic relationship with Rhizobium bacteria in their root nodules. Amaranth, Purslane, and Spinach are not typically classified as nitrogen-fixing plants.
