the passage of the Fugitive Slave Act

the admission of Kansas as a free state

the admission of California as a free state

a ban on the slave trade in Washington, DC

The admission of Kansas as a free state

Explanation:

The Compromise of 1850 consisted of four major provisions that aimed at defusing political confrontations that have originated on the issue of whether to allow slavery in the U. S.'s new western land that Americans had acquired in the Mexican-American War.

Under the Compromise, a new Fugitive Slave Act was enacted to require citizens of free states to assist in capturing fugitive slaves or to face fines or imprisonment, California was admitted as a free state, Congress gave "popular sovereignty" to the territories of New Mexico and Utah to decide whether to allow slavery and slave trade was banned in Washington, DC, although slavery continued to be legal there.

However, Kansas was nowhere mentioned in the Compromise. It wasn't until the Kansas-Nebraska Act that this territory was organized under the principle of popular sovereignty that allowed white residents to decide whether to allow slavery.
