Who was married to Sakakawea and served as a translator for Lewis and Clark?

Sakakawea was married to Toussaint Charbonneau, who played a significant role in the Lewis and Clark Expedition as a translator. Charbonneau, a French-Canadian fur trader, had brought Sakakawea with him as his wife. Her knowledge of the Shoshone language and connections to tribal leaders were crucial for the success of the expedition, particularly during encounters with various Native American tribes.

As the group embarked on their journey in 1804, Charbonneau's ability to communicate between the expedition members and the Native populations they encountered was invaluable. This collaboration ultimately contributed to the success of Lewis and Clark in their quest to explore and map the newly acquired western territories of the United States.

The other individuals in the options do not have a connection to Sakakawea or the specific role of translator in the Lewis and Clark Expedition, making Charbonneau the correct answer.
