When an aircraft's pilot is executing a maneuver in response to a TCAS Resolution Advisory (RA), what is the legal separation responsibility of the air traffic controller?

1. The controller is temporarily released from responsibility for separating that aircraft from other traffic until the RA is resolved
2. The controller must immediately issue an opposing vector to the other conflict aircraft to assist the pilot
3. The controller retains full separation responsibility and must override the TCAS climb or descent
4. The controller must coordinate with military radar to take over the sector
