Recent studies on giraffes across Africa suggest that they constitute<u> four</u> different species.
<h3><u>What various giraffe species are there?</u></h3>
Genetics underlies the differentiation between a species and a subspecies. A new species is distinguished from a subspecies when there are sufficiently large genetic differences between groups of the same species that prevent individuals from the two species from mating and conceiving viable offspring.
In other words, no other group of animals can be used to replicate the gene pool of a species because it is wholly unique to that group of animals. The southern giraffe population is increasing, in contrast to the other three giraffe species. A subspecies of the southern giraffe, the Angolan giraffe is mostly found in Namibia and Botswana.
An additional subspecies, the South African giraffe, is found in portions of Botswana, Zimbabwe, Angola, Zambia, South Africa, and Mozambique.

The doctrine of nullification was coined by Vice President of South Carolina, John C. Calhoun in 1828, by anonymously drafting a pamphlet titled 'South Carolina Exposition and Protest.'

So, the best definition of nullification is in option B. Therefore, option B is correct.
