What most accurately identifies and explains a cause of California quick transition to statehood?

The idea that the United States was destined to expand its territory across the North American continent was a major factor in California's quick transition to statehood. This belief was popular in the United States in the 19th century, and it was used to justify the annexation of Texas and the Mexican-American War. After the Mexican-American War, the United States acquired California as part of the Treaty of Guadalupe Hidalgo. The discovery of gold in California in 1848 led to a massive influx of settlers, and California quickly became a major economic and political center. In 1850, California was admitted to the Union as a free state, making it the 31st state.

* The large number of American settlers in California.

* The rapid economic growth of California.

* The desire of the United States to expand its territory.

* The political instability of Mexico.

These factors all played a role in California's quick transition to statehood.
