Answer: B. Priests were chosen as tribal leaders.
Explanation: The Paleolithic period extended from the origin of man to about 10,000 BC. Christianity did not exist at that time, so it would be impossible for priests to be chosen as tribal leaders.
Paleolithic society was characterized by the search for subsistence, that is, individuals sought everything that was necessary to sustain life by hunting, fishing, collecting fruits, seeds and roots, and the making and use of objects of chipped stone, bones and teeth of animals.
In these societies, men and women lived in small groups, dividing space and tasks and without distinction of classes. To protect themselves from the cold, the rain, and the ferocious animals, they sought shelter in the caves or recesses of rocks.
