To understand the answer to this question, we need to have an understanding of broadcast domains and switches.

A broadcast domain is a logical division of a computer network, where all devices can reach each other through broadcast messages. Broadcast messages are packets that are sent to every device on a network segment, and they are used to perform tasks such as network discovery, address resolution, and other network management functions.

A switch is a networking device that connects devices together in a network, allowing them to communicate with each other. A switch operates at the data link layer of the OSI model and is responsible for forwarding frames between network segments.

Now, let's look at the question. It asks how many broadcast domains are created when using an unmanaged 12-port switch. An unmanaged switch is a switch that does not have any configuration options and operates as a plug-and-play device.

In this case, each port on the switch represents a separate network segment, and each segment is its own broadcast domain. So, the number of broadcast domains created by an unmanaged 12-port switch is equal to the number of ports on the switch, which is 12.

Therefore, the correct answer is E. 12.

Note that this answer assumes that there are no VLANs configured on the switch. If VLANs are configured, then the number of broadcast domains would be different, depending on how the VLANs are configured.
