D. absorb minerals is the most correct option .The fungi that form mycorrhizal associations with plants play an important role in facilitating the uptake of nutrients, particularly minerals such as phosphorus, by the plant roots.
These associations also help to improve the overall health and growth of the plant. Therefore, pollutants that destroy these fungi would directly impact the plant's ability to absorb minerals, primarily. Without the mycorrhizal associations, the plant would not be able to obtain sufficient amounts of essential nutrients, which would lead to stunted growth, reduced vigor, and decreased productivity.
While all of the processes listed in the answer choices are important for plant growth and survival, the direct impact of pollutants on the plant's ability to absorb minerals. answer choice D - absorb minerals - the most correct option.
