View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
Both statements are exact NCERT quotes. NCERT states “Biofertilisers are organisms that enrich the nutrient quality of the soil” and “The main sources of biofertilisers are bacteria, fungi and cyanobacteria.” The Reason explains WHAT biofertilizers are (nutrient-enriching organisms) that enables the taxonomic sources listed in the Assertion to function as biofertilizers.
