Question

a result of the sectional crisis over california in 1850 was that

northern states considered leaving the union.
president taylor tried to compromise.
northern politicians banned slavery.
southern states considered leaving the union.

Explanation:

The question is about the sectional crisis over California in 1850. Among the options, "Southern states considered leaving the Union" is correct because the Southern states were concerned about the balance of free and slave states with California's admission as a free state, leading to talk of secession. "Northern politicians banned slavery" is incorrect as they didn't ban slavery nationally. "President Taylor tried to compromise" – Taylor's stance was more about California's admission without strict compromise efforts in the same way as later, and the main reaction from the South was considering secession.

Answer:

The correct option is: Southern states considered leaving the Union.
