The correct option is C Endomitosis
Endomitosis leads to polyploidy. Endoreplication or endomitosis is a replication of the nuclear genome in the absence of cell division, which leads to an elevated nuclear gene content and polyploidy. Endoreplication can be understood simply as a variant form of the mitotic cell cycle (G1–S−G2−M), in which mitosis is aborted prior to cytokinesis or circumvented entirely, due in part to a modulation of cyclin-dependent kinase activity.
