The use of geospatial intelligence $($GEOINT$)$ is one component of the U$.$S$.$ Border Patrol's technical method for gaining situational awareness along the border. The use of GEOINT involves gathering and analyzing imagery and geospatial information for the purpose of detecting change within specific geographical areas along the U$.$S$.$ border. GEOINT resources are used to maintain situational awareness in areas with a lower density of Border Patrol Agents when persistent deployment is not feasible due to terrain or location.

From the information given above, it can be validly concluded that, in order to be able to maintain the U$.$S$.$ Border Patrol's situational awareness along the border,

A$)$ If it is feasible to have persistent deployment of Border Patrol Agents, then GEOINT resources maintain situational awareness

B$)$ GEOINT resources must be maintained alongside persistent deployment of Border Patrol Agents

C$)$ If GEOINT resources do not maintain situational awareness, then it is not feasible to have persistent deployment of Border Patrol Agents

D$)$ there may be some areas in which situational awareness cannot be maintained either through the deployment of Border Patrol Agents or the use of GEOINT

E$)$ GEOINT resources maintain situational awareness if it is not feasible to have persistent deployment of Border Patrol Agents
