Why each option
MAC filtering improves wireless network security by allowing only devices with pre-approved MAC addresses to connect, blocking unauthorized clients.
MAC filtering does not encrypt traffic - encryption is handled by protocols like WPA2/WPA3, which are separate from MAC filtering.
MAC filtering does not hide the network SSID - network visibility is controlled by enabling or disabling SSID broadcast.
MAC filtering has no relationship to IP address assignment - static vs. dynamic IP is a DHCP configuration concern.
MAC filtering works by configuring the wireless access point to accept connections only from a whitelist of known MAC addresses. Any device whose MAC address is not on the list is denied association, which adds a layer of access control and makes the network more secure against unauthorized users. While not foolproof against spoofing, it does raise the barrier to entry.
