A. allow slavery in land obtained from Mexico

B. ban slavery in land obtained from Mexico

C. ban slavery south of the Rio Grande

D. offer to buy additional land from Mexico

Option B. Wilmot Proviso was a United States Congress proposal to ban or prohibit slavery in land obtained from Mexico.

Explanation:

During 1846, an encounter between military guards and Texas ignited United States-Mexican war. United States Congress tried a peaceful solution by negotiating with Mexico with a proposal to offer a ransom of $30000 and additional $2 million to Mexican President, James K. Polk in return of acquiring Oregon territory and a major share of Texas from Mexico.

Fearing a threat of slavery, United States Congressman, David Wilmot put forth this proposal during 1846 so as to prohibit slavery in the region post United States-Mexican war. Although bill was passed by House, Senate later adjourned this amendment without Provison and subsequently approved the funds negotiated.

The correct answer is B: ban slavery in land obtained from Mexico

Explanation:

The Wilmot Proviso was an unsuccessful 1846 proposal in the U. S. Congress.

In 1846 it passed the House as an amendment to the $2,000,000 appropriations bill to negotiate the end of the war, but failed in the Senate.

In 1847 it was reintroduced but also passed the House and failed in the Senate.

Finally, in 1848, an attempt was made to make it part of the Treaty of Guadalupe Hidalgo, but it also failed. Political controversies over slavery in the southwest persisted until Compromise of 1850.
