Letter E is the correct answer.

During the 1840, Hispanics lost ownership of large areas of lands in California.     The Treaty of Guadalupe Hidalgo (1848) marked the end of the Mexican-American War, which forced Mexicans to give up on 55% of their territory. The huge chunk of territory added to the United States corresponds to not only California but also Arizona, Colorado, Nevada, Utah, Wyoming and New Mexico.
