Final answer:
On their trip home, Lewis and Clark did not fight and split up, but were guided by Sacagawea to find Saint Louis.
Step-by-step explanation:
On Lewis and Clark's trip home, they did not fight each other and split up (C). Instead, Sacagawea played a crucial role in helping them find Saint Louis (D). She acted as their guide and interpreter, leading them through unfamiliar territory and facilitating communication with the Native American tribes they encountered. While Lewis and Clark did explore more territory (B) during their expedition, this question specifically asks about their return journey, during which they relied on Sacagawea to find their way back.
