Solution
The correct option is D Nucleolus
A conspicuous rounded body present in the nucleoplasm and attached to a particular chromosome at a definite place is nucleolus.
It is a small, dense and spherical structure present in the nucleus of the cell that is visible during the interphase of the cell division under the microscope.
This region is dense due to the presence of proteins, DNA and RNA which are formed from specific chromosomal regions called nucleolar organizing regions.
