Solution

The correct option is D All of the above
Constitutive heterochromatin is a certain region of DNA found on the chromosomes of a eukaryotic cell.
The constitutive heterochromatin gets darkly stained due to the highly condensed nature of the DNA in these regions.
This heterochromatin is made up of high copy number tandem repeats (repetitive nucleotides).
So, the correct answer is 'All of the above'.
