Answer:
Option C, They allow random distribution of genetic material when a cell divides.
Explanation:
The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.  
Chromosomes make recombination and random segregation of genetic material to form new cells.  Each new cell gets equal number of chromosomes 
Hence, option C is correction

The correct answer is option C-glycogen
Glycogen is an immediate source of energy in animals. Glycogen is formed of small sub-units called glucose monomers. The process of formation of glycogen is called glycogenesis.  
Glycogen is animal equivalent to starch.  
When body need energy, the stored glycogen breaks down into small monomers called glucose and provide energy to the cell.  
The excessive amount of glycogen is stored in muscles and liver.
