When a cell is getting ready to divide, the DNA will coil itself with the help of proteins into a chromosome.
A spooled string of genes packaged in a single unit is called a chromosome. A chromosome is a structure of DNA, RNA, and protein which are found in cells.
genome -> chromosome -> DNA -> gene
The difference between a chromosome and a DNA molecule is that a chromosome is a single DNA molecule associated with proteins and a DNA molecule is a long thin molecule that stores genetic information.
The second statement would be more correct.
By proteins called histones.

From loose to tight in order of DNA, histones, nucleosomes, 30 nm fiber, looped domains (300 nm fiber), then metaphase chromosome (700 nm chromatid).

every and any DNA strand can constitue to a chromosome :)
The second statement would be more correct.
this is incorrect question, because the size of the DNA is not specified. Without the DNA, it is chromosome > nucleosome > nucleotide. The actual DNA cannot be longer than a chromosome and nucleotide is a monomer of polymeric DNA, so DNA should be somewhere between chromosome and nucleotide.
