Double rod of condensed chromatin
A
centriole
B
centromere
C
spindle fibers
D
chromosome
Explanation: 

Detailed explanation-1: -chromosome – A double rod of condensed chromatin. 6. cytokinesis – The final stage of the cell cycle, in which the cell’s cytoplasm divides, distributing the organelles into each of the two new cells.

Detailed explanation-2: -During prophase, the threadlike chromatin in the nucleus condenses to form double-rod structures called chromosomes.

Detailed explanation-3: -In a non-dividing cell the genetic material is present in the form of a thread-like structure called chromatin. During cell division, the chromatin is condensed to form a chromosome which acts as the rod-shaped structure. This rod-shaped structure helps in the separation of genetic material in the dividing cells.
