The correct answer is A. domino theory.

To understand why the United States became militarily involved in Vietnam, we need to examine the concept of the domino theory. The domino theory was a belief held by U.S. policymakers during the Cold War. It suggested that if one country in a region fell to communism, neighboring countries would also become communist, like a row of dominoes falling.

In the context of Vietnam, the U.S. government feared that if South Vietnam fell to communist forces, it would have a domino effect, leading to the spread of communism throughout Southeast Asia. The U.S. officials believed that winning the war in Vietnam was crucial to preventing the spread of communism in the region.

Therefore, in an effort to support South Vietnam and prevent the spread of communism, the United States gradually escalated its military involvement in Vietnam starting in the 1960s. This involvement included sending troops, providing military aid, and engaging in combat operations.

To sum it up, the United States became militarily involved in Vietnam due to the belief in the domino theory, which stated that the spread of communism needed to be contained to prevent it from taking over neighboring countries.
