The correct response that accurately describes how the Bantu migration changed Africa's cultural landscape is:
The Bantu brought knowledge of iron tools and weapons.
The Bantu migration, which occurred over several centuries, significantly influenced the cultural and technological development of sub-Saharan Africa through the introduction of ironworking techniques, which enhanced agricultural productivity and warfare. This led to the establishment of more complex societies and the spread of Bantu languages and cultural practices across much of the continent.
