The correct option is C Myxomycetes
Myxomycetes, also called as mycetozoa, phylum of fungus-like organisms within the kingdom protista, commonly known as true slime molds. They exhibit characteristics of both protozoans (one-celled microorganisms) and fungi. Myxomycetes is a class of slime molds, formerly regarded as animals (Mycetozoa), but now generally thought to be plants and often separated as a distinct phylum (Myxophyta); equivalent to the division Myxomycota. They are found on damp earth and decaying vegetable matter and consist of naked masses of protoplasm, which creep very slowly over the surface and ingest solid food.
