The correct option is
B Saprophytic fungi
Vesicular-Arbuscular Mycorrhiza (VAM) is formed by the symbiotic association between certain phycomycetes fungi and angiosperm roots. The fungi colonize the root cortex forming a mycelial network and characteristic vesicles (bladder-like structures) and arbuscules (branched finger like hyphae). Hence, VAM is a symbiotic fungus.
So, the correct answer is 'Symbiotic fungi'.
