The correct option is C rhizomes
The horizontal stems of ferns are called rhizomes. Rhizomes have a growing tip that produces fronds. They are underground and they help in absorption of water and nutrients.
The large green and feathery leaves of ferns are called fronds.
Rhizoids provide anchorage in bryophytes. They are not roots, but they are outgrowths from the thallus.
Rhizophore is found in Selaginella. It originates from the stem at the point of branching and grows downwards forming adventitious roots.
