Which outcome results when leguminous plants experience a manganese deficiency?

A)Decreased nitrogenase enzyme activity
B)Increased susceptibility osmotic stress
C)Enhanced phosphate transport efficiency
D)Reduced chlorophyll biosynthesis rates

💡 Explanation

Manganese deficiency decreases nitrogenase activity because manganese acts as a cofactor for the nitrogenase enzyme, crucial in nitrogen fixation. Therefore, nitrogen fixation is impaired; rather than enhanced nutrient uptake of other elements.
