Roots of most terrestrial plants are colonized by symbiotic mycorrhizal fungi. These fungi are capable of mobilizing inorganic phosphates or compound phosphates present in the soil to the plant an a source of Phosphorus.

Full form of VAM is Vesicular-Arbuscular Mycorrhiza. It is formed by the symbiotic association between certain phycomycetous fungi and angiosperm roots. Thus VAM is a mycorrhiza.

Symbiotic association between roots of higher plants and fungi is termed as mycorrhiza.

Fungi forms symbiotic association with roots of higher plants, known as mycorrhizae. When fungal hyphae penetrate through cortex cells of root, these are called as Endomycorrhizae. These are also called vesicular arbuscular mycorrhizae or VAM, because cortical cells swell and form vesicles or arbuscles. it has significant role in phosphorus nutrition in plants. hence, Option A is correct. 

Mycorrhiza is an association between a fungus and the root of the higher plant, for example, pinus, eucalyptus etc.

Mycorrhiza is a type of symbiotic relationship. It is seen when two organisms have mutually beneficial relationship with each other. In this cas, the roots of plants host fungi, which helps them obtain water, sulphur, phosphates from soil. They also help them fix nitrogen. Inturn, fungi obtain nutrition and shelter 

Fungi present in the roots of the plants show a symbiotic relationship with each other. It helps the roots of the plants to absorb more nutrients and water from the soil. It also helps them obtain better resistance to environmental stresses. In return, plants provide shelter and nutrition to mycorrhiza.

Mycorrhiza is a symbiotic relation seen between certain plants and fungi. The fungi live on the roots of certain plants and help them absorb water and nutrients from the soil in a better way. In return, plants provide shelter and nutrition to fungi. So, both the organisms mutually befit each other.
