The Ohio River Valley was the primary land in dispute between the French and the British largely due to the region's abundant natural resources, particularly the lucrative fur trade that the French had established there. Both the British and their American colonists were eager to expand into this territory to gain access to its wealth and to secure land for settlement. This competition for control of the region was a significant factor leading to the clashes that erupted into the French and Indian War (1754–1763), which is also known as the Seven Years' War when considering the global conflict.

Thus, the correct statement would be:

"The region had lots of natural resources and the French had established a strong fur trade there while the British and the colonists wanted to start expanding into the territory."
