Mycorrhizal fungi are
a. mutualistic root-dwelling fungi that plants obtain more water and nutrients.
b. mutualistic leaf-dwelling fungi that obtain sugar from plant leaves
c. parasitic leaf-dwelling fungi that strangle plants
d. epiphytic plants living on plant stems and leaves

The answer is a. mutualistic root-dwelling fungi that help plants obtain more water and nutrients.

A mutualistic relationship between fungi and plants is known as mycorrhiza. Mutualism is a relationship between two different species in which both species have benefits. In mycorrhiza, the fungi get the product of photosynthesis in plants, and plants absorb water nutrients (phosphorus and nitrogen) through fungi.
