The correct answer is B. They never developed wheeled vehicles.
Step-by-step explanation
During the development of civilizations the help of different animals has been of great importance, in many cases dogs became the best friends of hunters because they helped them find and hunt their food, in other situations horses were a great help to transport over long distances, other animals such as oxen contributed to making agriculture easier by moving heavy tools to make the furrows of the crops, among others. Over time, communities invented tools that optimized the help provided by animals, in the case of horses, many civilizations developed carts and carriages that were pulled by horses to transport heavy objects, people, and products easily. However, the American civilizations that did not have access to horses (which came from Europe) until the conquest of Europeans could not develop complementary tools for their animals so in effect they never developed wheeled vehicles. Therefore, the correct answer is B. They never developed wheeled vehicles.
