Explanation

A firewall (B) commonly performs NAT (Network Address Translation), translating private internal IP addresses into a public IP address for outbound Internet traffic. In most SOHO (small office/home office) environments, the firewall or router/firewall device handles NAT. NAS (Network Attached Storage) is a file storage device and does not perform NAT. A hub is a basic Layer 1 device that simply repeats signals to all ports - it has no IP awareness whatsoever. A bridge operates at Layer 2 to connect network segments but does not perform IP address translation. Among the listed options, the firewall is the device responsible for NAT.
