This response emphasizes the strategic advantage that the Iroquois could provide by understanding the tactics and movements of the enemy, which would be crucial in executing a successful surprise attack. Additionally, it aligns with their experience as skilled warriors and knowledge of the local terrain and various fighting styles.
While the other options contain valid points, such as knowledge of the area and instructing British troops on woodland fighting, the insight into the enemy's habits and planning accordingly is the most directly relevant to the context of a surprise attack.
