Answer: A

Explanation:

Type = 12 is the type of ICMP error message received by Jaden in the above scenario. ICMP (Internet Control Message Protocol) is a protocol that sends error and control messages between network devices. ICMP error messages are categorized by types and codes, which indicate the cause and nature of the error. Type = 12 is the type of ICMP error message that indicates an IP parameter problem, which means that the IP header field contains invalid information. Type = 8 is the type of ICMP message that indicates an echo request, which is used to test the connectivity and reachability of a destination host. Type = 5 is the type of ICMP error message that indicates a redirect, which means that a better route to the destination host is available. Type = 3 is the type of ICMP error message that indicates a destination unreachable, which means that the destination host or network cannot be reached.
