Answer: C. It led many to question the loyalty of New Mexicans.
Step-by-step explanation:
New Mexico was a part of Mexico when they got independence from Spain but the Americans occupied it during the Mexican-American war and subsequently took control with the Treaty of Guadalupe Hidalgo.
In response to apparent mistreatment by American soldiers as well as land ownership concerns, the New Mexicans and their Pueblo allies rebelled against the U.S.. The rebellion was crushed but the damage was done as other Americans questioned the loyalty of New Mexico so much so that they were only granted statehood sex decades later.
