C. If assertion is true but reason is false
Step-by-step solution
Fungi are considered ubiquitous i.e. they occur in a variety of habitats. Most of them are moisture loving and terrestrial and few (eg. Monoblepharis) are aquatic. Fungi may be epiphytic (i.e. live on plants eg. Armillaria), saprophytic (i.e. grow in dead organic matter eg. Mucor), symbiotic (i.e. live with association with other plants eg. lichen, mycorrhiza) and predacious (eg. Dactyldela) and parasitic (eg Erysipi) fungi are achlorophyllus i.e. devoid of chlorophyll hence cannot prepare their own food. They are heterotrophic and show absorptive type of nutrition.
