Final answer:
The French aimed to take over the Natchez tribe’s land primarily for agricultural purposes, such as planting tobacco, due to the fertile land along the Mississippi River.
Step-by-step explanation:
The French wanted to take over the Natchez tribe’s land primarily to gain fertile land to plant tobacco and other crops, as agriculture was a significant aspect of the colonial economy. The Natchez region, with its advantageous position along the Mississippi River, was seen as valuable for its agricultural potential. This was in line with the broader French strategy in North America, which, despite its diverse and complex nature, also often involved the quest for commercially viable colonial outposts that could provide resources and wealth for the homeland. Therefore, the correct answer among the options provided is to gain fertile land to plant tobacco and other crops.
