Correct Answer - C
The roots of some higher plants are associated with fungal mycellia. Such an association is called nycorrhiza. It represents a mulualistic (symbiotic) association between the roots system of higher plants and fungal hyphae.The fungal hyphae form a network around the young root and invade the root cells. The extrnal hyphae greatly increase the surface area for absorption of minerals and water from a much larger volume of soil that perhap the roots alone cannot do.
