Eukaryotic cells have well-developed organelles. The cells consists of nucleus, inside which DNA is packaged in chromosomes. The chromosomes provide an advantage to the cell that is:

Option C. They allow random distribution of genetic material when a cell divides.

The DNA is packaged in the chromosome with the help of chromatin. The packaging of chromosomes makes it easy for the cell to undergo meiotic division. When the cell divides during meiosis:

Homologous chromosomes are randomly distributed in the daughter cells.The different chromosomes are segregated independently, following the law of independent assortment.This independent assortment of chromosomes leads to variation and unique combination of chromosomes.

Therefore, the random distribution of chromosomes provide variation and unique combinations.

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 answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
