Answer:
The correct answer is B. John C. Frémont led the Bear Flag Revolt during the war with Mexico.
Explanation:
When the Mexican-American War broke out in 1846, Frémont was promoted to the rank of major; shortly thereafter, on June 14, 1846, in the city of Sonoma, the American settlers encouraged by Frémont proclaimed the Republic of California, or Republic of the Bear, a supposedly independent state that lasted only 25 days before the self-proclaimed authorities of this Republic dissolved and handed over control of the territory to the United States Government that incorporated it into the American national territory.
