The . . . . . . . animal was on the look out for food.

uncivilized
wild
primitive
savage

The correct answer is B. wild.

A wild animal is an animal that lives in the natural world, not in captivity. Wild animals are not domesticated, and they may be dangerous to humans.

The other options are incorrect because they have negative connotations. Uncivilized means not having the customs or manners of a civilized person. Primitive means belonging to an early stage of human development. Savage means violent or cruel.
