C) Most fungi get their nutrients by ingesting small pieces of other living organisms.

Explanation:

Most fungi are saprotroph, it is, they obtain  nutrients by decomposing  non-living organic matter -i.e.  dead plant or animal matter-  and absorbing soluble organic compounds; carbohydrates are the preferred carbon source.

A smaller percentage of fungal species are parasites, and obtain nutrients from living hosts (other living organisms).
