Why each option
To limit wireless signal bleed into the parking lot, adjusting antenna placement and reducing transmit power levels are the two most effective physical controls that directly reduce signal range.
Antenna placement determines the direction and coverage area of the wireless signal; repositioning or using directional antennas can focus the signal away from the parking lot. Combined with adjusting power levels (F), organizations can tune the exact coverage footprint to prevent signal from reaching unintended areas.
Introducing interference would degrade the wireless network for legitimate users and is not a recognized security control.
WEP is a deprecated and easily cracked encryption protocol that does not reduce signal range.
Single Sign-On is an authentication mechanism and has no effect on wireless signal coverage.
Disabling the SSID broadcast hides the network name but does not reduce the physical range of the wireless signal.
