Which doctrine asserted the U.S. right to intervene in Latin America to maintain stability?

The Roosevelt Corollary is the correct answer because it expanded upon the Monroe Doctrine by asserting that the United States had the right to intervene in Latin American countries to prevent European intervention and to maintain stability in the region. This doctrine was articulated by President Theodore Roosevelt in 1904 and was a response to concerns that European nations might use military force to collect debts from Latin American countries.

The rationale behind this policy was that instability in Latin America could lead to European powers taking control, which the U.S. viewed as a threat to its sphere of influence and security. The Roosevelt Corollary effectively positioned the U.S. as a police power in the Western Hemisphere, emphasizing the U.S. commitment to maintaining order and preventing foreign intervention. This policy framed U.S. intervention as necessary for promoting stability and democracy in the region.

While other options like the Big Stick Policy and Dollar Diplomacy also relate to U.S. foreign policy in Latin America, they do not specifically highlight the assertion of the right to intervene as clearly as the Roosevelt Corollary does.
