A. Chromosomes are strands of DNA, tightly wrapped up, that are located in the nucleus.
B. Chromosomes are strands of RNA, tightly wrapped up, that are in the cytoplasm.
C. Chromosomes are strands of RNA, loosely wrapped up, that are located everywhere in the cell.
D. Chromosomes are strands of DNA, tightly wrapped up, that are located everywhere in the cell.

The statement that says "Chromosomes are strands of DNA, tightly wrapped up, that are located in the nucleus" is correct regarding chromosomes.

Chromosomes are the highly organized structures inside biological cells, made up of DNA and other proteins, and where most of an individual's genetic information resides.

Chromosomes have a double structure, composed of two structures parallel to each other and joined by a centromere, called chromatids.

In eukaryotic cells (with a defined nucleus), the chromosomes are elongated and found in the nucleus, while in prokaryotic cells, such as bacteria, these appear as circular rings closed in the nucleoid.

The chromosome allows the DNA information to be conserved and evenly distributed.

Therefore, we can conclude that chromosomes are condensed strands or rings of DNA and are located in the nucleus of cells when they are not dividing.
