Answer
Radicle
Reason — Radicle develops to form root.
The coleorhiza is a protective sheath around the radicle in monocot seeds. It does not itself develop into the root; it only protects it. The plumule develops into the shoot, not the root. The coleoptile is a protective sheath covering the plumule in monocots. It helps the shoot emerge through soil.
