The Inuit dog, an arctic breed said to predate the European colonization of the Americas, descends from a precolonial dog population. The Inuit dog carries a haplotype (a group of genetic variants inherited together from one parent) absent in European dogs but present in East Asian dogs, supporting the idea that precolonial breeds in the Americas descend from dogs that accompanied human migration from Asia in the last ice age. The Carolina dog, a yellow-coated breed native to the rural Southeastern US, offers further support. Present-day individuals carry haplotype A184, part of a haplotype group unique to East Asian dogs. Many other precolonial breeds, such as the Hare dog of Canada, vanished through interbreeding with dogs brought from Europe.

hardWhich finding, if true, would most directly undermine the underlined claim?
A
Haplotype A184 is present in precolonial remains recovered from Arctic North America, where the Inuit dog originated, as well as in remains from other regions outside the Southeastern US.
B
Several modern East Asian breeds were imported to the Southeastern US in the 1900s, and the Carolina dog’s recent ancestry may include individuals from these breeds.
C
The Carolina dog carries some genes that are also common in the remains of European dogs from before the European colonization of the Americas.
D
Haplotype A184 is present in dog remains recovered in East Asia and dating to before the emergence of the Carolina dog.
