Which option contains all of the other options listed? gene
chromosome
chromatid
centromere

The chromosome contains all of the other options listed.

Explanation:

In eukaryotes, the complete chromosome is composed of only one lineal and extremely long DNI molecule. DNA is intimately associated with two types of proteins: histones, which are structural proteins, and non-histone proteins that mediate different functions of DNA. DNI associated with histones is called chromatin. Histones are responsible for packaging the DNI molecule.

In the interphase, before cellular division, chromatin is in a diffuse, lax, uncondensed state. When cellular division is about to happen, chromatin begins to condensate, and the chromatin strand generates a copy or clon so both of the daughter cells can get the same genetic information. At the beginning of the prophase, DNI is condensed in a well-defined chromosome formed by two sister chromatids. In metaphase, two chromatids joined by a centromere form the typical chromosome.

So, one chromosome is composed of two sister chromatids condensated and joint by the centromere. It looks X-shaped.

Genes are located in chromosomes, specifically in the DNA strand.
