How did the manifest destiny deepen divisions among us citizens?

by empowering a nationalist revolutionary movement

by forcing native Americans to move westward to reservation lands

by undermining calls to defend the annexation of texas

by igniting debate over the expansion of slavery

The correct answer is "By igniting debate over the expansion of slavery."

Every time the US wanted to add another state to our country, the issue of slavery would inevitable come up. This caused a huge division between Northerners and Southerners. Congress tried to compromise on this issue several times by making laws like the Missouri Compromise, Compromise of 1850, and the Kansas-Nebraska Act. However, these all failed at solving the issue and only lead to more tension between the North and South.
