Hint:Knowing the differences between variety and variability of living organisms can help understand the genetic diversity as it is the differences in DNA among individuals within a species or population.

Complete Answer:
Let’s try to define genetic diversity initially-
1) Genetic diversity is the differences in DNA among individuals within a species or population. It can be caused by mutation, random mating, random fertilization, and recombination between homologous chromosomes during meiosis. Examples of genetic diversity include:
2) A single species might show high diversity at the genetic level over its distributional range. The genetic variation shown by the medicinal plant Rauwolfia vomitoria growing in different Himalayan ranges could be in terms of the potency and concentration of the active chemical (reserpine) that the plant produces. India has more than 50,000 genetically different strains of rice.The measure of the genetic differences that exist within a population is called genetic variation.
3) The variety and variability of living organisms (both plants and animals) are known as biodiversity. The variation measured by biodiversity is at the genetic, species, and ecosystem level. Gene-based diversity is known as genetic diversity. It is a way for populations to adapt to changing environments.

Additional information:
The genetic variation of an entire species is often called genetic diversity.
>Genetic variations are the differences in DNA segments or genes between individuals and every variation of a gene is known as an allele. It is essential for natural selection because natural selection can only increase or decrease frequency of alleles which already exist in the population.

Hence, the correct answer is option C (Gene based diversity).

Note: Genetic diversity is the level of biodiversity, refers to the total number of genetic characteristics in the genetic makeup of a species.
