Answer:
To attract more settlers for the territory.
Explanation:
Pierre Le Moyne d'Iberville was a French soldier, explorer, knight, and ship captain who founded the first French colony for King Louis XIV. This colonial expansion was a result of a competition among the powers such as the British empire.
After the establishment of the colony at Fort Maurepas, d'Iberville returned to France to get supplies for the settlers in the colony. Moreover, the objective was to gain more settlers to accompany him to the colony and also to get more soldiers to help secure the colony against any attackers. And while he was in France, the Fort was attacked by the Chickasaw, an ally of the British empire.
Thus, the correct answer is the last option.
