The statement that most accurately describes the terms of the Compromise of 1850 is:
California was allowed to enter the Union as a free state with no slavery.
Additionally, the Compromise of 1850 included other provisions such as the establishment of popular sovereignty in the territories of New Mexico and Utah (allowing them to vote on whether or not to permit slavery) and the resolution of boundaries and debts related to Texas, but it did not eliminate all slavery in the District of Columbia; instead, it allowed for slavery to continue there while also banning the slave trade.
