The correct answer is "As the sectional crisis over California intensified in 1850, D. Southern states considered leaving the Union"

Explanation:

The Compromise of 1850 was supposed to solve the crisis between North and South and to decide what to do with the new territories won in the Mexican-American War: California would be incorporated as a free state, and Texas would have a slave-based constitution.

The North did not support slavery and believed in governing the Union as one people due to their majority. However, the South were fighting for less centralized government so each state would be able to govern itself. With California as a free state, the North had more power in the Senate and refused to enforce the Fugitive Slave Law. This increased tensions and Southern states considered leaving the Union.
