Explanation

MAC filtering allows an administrator to create an allowlist of approved device MAC addresses, permitting only those devices to connect to the wireless network. Without an authentication server, this is the only listed option that directly restricts access based on device identity. Antenna placement (A) and power level adjustment (B) control the physical range of the signal but do not authenticate or restrict individual devices. Disabling SSID broadcasting (C) provides only obscurity - the network can still be discovered by anyone scanning for wireless networks, and it does not prevent unauthorized devices from connecting if they know the SSID.
