Explanation

A hub is a Layer 1 device that broadcasts all incoming traffic to every connected port, meaning any device on the network can see all traffic - making it trivially easy to sniff packets. A switch (Layer 2) forwards traffic only to the intended port, a router (Layer 3) can enforce ACLs and segment networks, and a firewall is purpose-built to filter and control traffic. The hub offers zero traffic isolation and therefore the least security.
