Which of the following was NOT a provision of the Compromise of 1850?

The Compromise of 1850 was a set of legislative measures aimed at resolving disputes related to slavery and territorial expansion following the Mexican-American War. Among its key provisions was the admission of California as a free state, the establishment of popular sovereignty in the Utah and New Mexico territories (allowing residents to vote on whether to permit slavery), and the banning of the slave trade in Washington D.C.

However, the immediate abolition of slavery was not part of the Compromise. Instead, the compromise aimed to maintain a delicate balance between free and slave states without making abrupt changes to the institution of slavery itself. This is why the answer is correct: the Compromise did not include any measures for the immediate abolition of slavery anywhere in the United States. It sought to appease both pro-slavery and anti-slavery factions without taking such drastic action.
