The correct statement that compares the views of John C. Calhoun and Angelina Grimké about slavery is:
Calhoun believed individual states should decide the issue of slavery, while Grimké argued for immediate emancipation.
Calhoun was a proponent of states' rights and defended slavery, believing that individual states should have the authority to decide whether to permit it. In contrast, Grimké was an abolitionist who advocated for the immediate emancipation of enslaved people.
