Explanation:

• First question:
• A MAC (Media Access Control) address is a 48 - bit address usually represented in hexadecimal format with six groups of two hexadecimal digits separated by colons or hyphens. Option A ($00 - AF - 03 - 05 - 0E - 89$) follows this format.
• Option B ($192.168.0.5$) is an IPv4 address.
• Option C ($192.684.168.255$) is an invalid IPv4 address (since octets in IPv4 range from 0 - 255 and 684 is out of range).
