Answer:
The correct answer is:
A. Stop undocumented immigrants from entering the United States through its southern border.
Step-by-step explanation:
The Clinton administration established Operation Gatekeeper with the primary goal of stopping undocumented immigrants from entering the United States through its southern border. This operation was implemented in 1994 and focused on increasing border security and surveillance along the U.S.-Mexico border. The intention was to deter unauthorized crossings and improve control over immigration flows. Operation Gatekeeper involved the construction of physical barriers, such as fences and walls, as well as the deployment of additional Border Patrol agents and resources to monitor and secure the border. The aim was to reduce the number of unauthorized entries into the United States and enforce immigration laws more effectively.
