To find the answer to which event contributed the most to San Francisco's population change, we need to review the options given and consider their historical context.

1. The Gold Rush: The California Gold Rush in the mid-19th century attracted thousands of people from all over the world to San Francisco in search of gold. This influx of miners and settlers had a significant impact on the city's population.

2. The Mexican-American War: The Mexican-American War, which took place from 1846-1848, resulted in the United States gaining control of California. While this event did lead to some population growth in San Francisco, it was not as significant as the Gold Rush.

3. The Monroe Doctrine: The Monroe Doctrine was a policy statement made by U.S. President James Monroe in 1823, outlining the United States' opposition to any further colonization or intervention by European powers in the Americas. This doctrine did not directly impact San Francisco's population change.

4. The Trail of Tears: The Trail of Tears refers to the forced removal and relocation of Native American tribes, primarily the Cherokee, from their ancestral lands in the southeastern United States to territories west of the Mississippi River in the 1830s. This event did not directly contribute to San Francisco's population change.

Based on this information, the Gold Rush is the event that contributed the most to San Francisco's population change.
