Explanation
Because the network must remain open (no passphrase), options that require credentials are off the table. Reducing the wireless access point's transmit power level shrinks the signal's coverage area so it only reaches the intended physical space (e.g., inside the business), making it difficult for a neighboring company to detect or connect. MAC filtering (B) could also work but requires ongoing maintenance of an allowlist and is easily spoofed. Content filtering (D) and firewall (E) don't restrict who can associate with the network. Changing the default SSID (A) only obscures the name.
