Solution:
The correct answer is:
Chromosomes are found in the nucleus of eukaryotic cells. A chromosome is a long macromolecular complex that packages a single DNA molecule and multiple proteins. Histones and other proteins organize DNA into compact arrays and help in the process of transcription and translation. Normally, each cell in the human body has 23 pairs of chromosomes, half of which come from the mother and half from the father. 1 pair of chromosomes (X and Y) determine male or female gender and are called sex chromosomes.
