Select a valid MAC address.

A valid MAC address must adhere to specific formatting rules. Standard MAC addresses are typically represented in six groups of two hexadecimal digits, each separated by colons or hyphens. They usually consist of a combination of numbers (0-9) and letters (A-F), making them two characters long per group.

The choice presented as 00:00:5E:80:EE:B0 fits this format perfectly—there are six groups of two hexadecimal digits separated by colons, which conforms to the standard representation of a MAC address. Each group ranges from 00 to FF, which is valid within hexadecimal notation. This makes it a valid and correctly formatted MAC address.

The other options either deviate from this accepted format or do not represent MAC addresses at all. For instance, the first option contains invalid characters and exceeds the standard character count for a MAC address. The third choice exceeds the six-group format for MAC addresses, suggesting it doesn’t conform to the standard specification. The last option is a network address, not a MAC address, which further disqualifies it from being considered valid in this context. Hence, the selection of 00:00:5E:80:EE:B0 is justified based on its proper adherence to MAC
