The correct answer is D. MAC filtering is blocking him.. If a laptop cannot connect to a wireless network despite a correct password, the most likely issue is MAC filtering, which prevents devices with unapproved MAC addresses from joining the network.

Why each option
If a laptop cannot connect to a wireless network despite a correct password, the most likely issue is MAC filtering, which prevents devices with unapproved MAC addresses from joining the network.
Operating system incompatibility is unlikely to prevent connection to a standard wireless network, as modern OSes support common Wi-Fi standards.
A firewall typically controls network traffic after a connection is established, not the initial association with a wireless access point.
Laptop incompatibility with standard Wi-Fi is rare for a 'new' laptop, as most modern devices support common wireless standards.
MAC filtering is a security measure where a wireless access point is configured to only allow devices with specific MAC addresses to connect, and if the new laptop's MAC address is not on the approved list, it will be blocked.
