Solution

The correct option is C Coiling of nucleosomes
Since the length of DNA molecule is manyfold greater than the length of the eukaryotic cell, the cell packages the DNA molecule along with packaging proteins called as histones. This leads to the supercoiling of DNA around the histones to form nucleosomes, and this greatly decreases the length of the DNA molecule, fitting it inside the eukaryotic cell.
