The correct answer to the question is mycorrhizae.

Explanation

Mycorrhizae are beneficial associations between plant roots and fungi that enhance nutrient uptake, particularly phosphorus, for the plants. In this symbiotic relationship, the fungal mycelium extends the root system of the plant, increasing the surface area for absorption of water and nutrients from the soil. In return, the plant provides the fungi with carbohydrates and other organic compounds produced through photosynthesis. This mutualism is essential for plant health, growth, and productivity, particularly in nutrient-poor soils.

While the other terms listed—mycelia, pneumatophores, mycophyta, and myrmecochores—refer to different biological concepts, they do not describe the specific symbiotic relationship characterized by mycorrhizae.
