Your answer is B.
Good luck with the rest!

The correct answer is option B, that is, mycorrhizal fungi were killed.

An essential element affecting uptake of minerals in some of the plants is the symbiotic relationship established between the root and a mycorrhizal fungus. The majority of the plants develop more gradually and relies on mycorrhizal relationships to extract soil-water and nutrient reserves in their competition with other plants.

Thus, with the application of fungicides the population of mycorrhizal fungi dies and therefore, the mechanism of mineral uptake gets affected. As a result, the plant develops a mineral deficiency.
