Solution
The correct option is C Stem
Fern stems are often called rhizomes, but this term refers to those with a long-creeping or climbing habit. If the stem is short and compact and radially symmetric, either erect, prostrate or ascending then it is called a caudex or rootstock. In some cases, the caudex is erect and tree-like with an apical radial tuft of leaves (Cyathea, Dicksonia, Leptopteris, some Blechnum, Thelypteridaceae) in which case it is often called a trunk. Creeping rhizomes can be either long-creeping with widely spaced fronds or short-creeping with fronds relatively close together. The rhizomes can be radial or radially symmetric or dorsiventral with leaves or fronds produced on the dorsal or upper side and roots produced on ventral or lower side.
Some plants have rhizomes that grow above ground or that lie at the soil surface, including some Iris species, and ferns, whose spreading stems are rhizomes. Plants with underground rhizomes include gingers, bamboo, the Venus Flytrap, Chinese lantern, Western poison-oak, hops, and Alstroemeria, and the weeds Johnson grass, Bermuda grass, and purple nutsedge. Rhizomes generally form a single layer, but in Giant Horsetails, can be multi-tieredSo, the correct answer is 'Stem'
