The form of DNA that is unorganized and unraveled.
A
Centromere
B
Chromatid
C
Karyotype
D
Chromatin
Explanation: 

Detailed explanation-1: -When a eukaryotic cell is not reproducing, its DNA is inside the nucleus as disorganized, long strands called chromatin. Before a cell divides, the chromatin thickens and shortens into distinctly visible bodies called chromosomes.

Detailed explanation-2: -NEW YORK (GenomeWeb) – Contrary to what was previously thought, chromatin is a disorganized chain that is packed together at differing densities during interphase and mitosis, according to a new study.

Detailed explanation-3: -During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes.

Detailed explanation-4: -The unraveled material from a chromosome that floats around in the nucleus is known as chromatin. These ribosomes are cell organelles made up of RNA and proteins; they are transported to the cytoplasm, which are then attached to the endoplasmic reticulum.
