Goat is not a wild animal amongst the given options.

On the basis of whether an animal can live in captivity and whose presence might benefit humans in some or the other way, animals are divided as wild and domestic. A wild animal who may or may not be born in wild, but cannot be tamed and is unfit to reside in human settlement. They prefer their natural environment and freedom. These animals include boar (wild pig), jackal, and bison. On the other hand, domestic animals like the horse or cat, can be tamed and kept by humans as a work animal, food source, or pet. They could be an entire species or certain members of species that have developed to become tolerant to human presence.
