Which risk increases where legume crops show stunted growth despite sufficient fertilizer application?

A)Insufficient molybdenum inhibits symbiotic enzymes
B)Increased soil salinity reduces aeration
C)Soil acidity restricts phosphorus uptake
D)Fungal diseases impair root nodule formation

💡 Explanation

Insufficient molybdenum leads to impaired nitrogen fixation because it is a cofactor for nitrogenase, a key enzyme; the legumes cannot convert atmospheric nitrogen to usable forms, therefore they show stunted growth, rather than experiencing salinity, acidity, or fungal issues directly affecting nodule formation.
