An example of endomycorrhiza is
Nostoc
Glomus
Agaricus
Rhizobium
The symbiotic relationship between fungi and the roots of higher plants is called mycorrhizal. Endomycorrhiza is a mycorrhizal mycelial system that grows near the roots of vascular plants, even on the roots. For example nephritis. Glomus is a genus of arbuscular mycorrhizal fungi.Species belonging to the genus Glomus form a symbiotic relationship with plant roots. Hence, option 2 is correct.
