Question Statement:
Read the passage: 'Unlike synthetic nitrogenous fertilizers that leach rapidly into groundwater aquifers during heavy rains, bio-fertilizers composed of mycorrhizal fungi establish long-term associations with host root hairs, continuously solubilizing bound phosphorus.' It can be inferred that:
Options:
- (A) Mycorrhizal fungi provide sustained nutrient availability with lower groundwater leaching risk than synthetic nitrogen.
- (B) Synthetic nitrogen is chemically identical to mycorrhizal fungi.
- (C) Phosphorus is water-soluble under all soil conditions.
- (D) Bio-fertilizers require heavy rain to solubilize nutrients.
