What is the main difference between a normal ICMP $($ping$)$ request and an ICMP flood? $($Select two.$)$

The normal ICMP ping request only has one source address.

With an ICMP flood, ICMP packets are sent and received at a quicker pace.

The only difference is the number of packets being sent.

With an ICMP flood, all packets come from the same source.

With an ICMP flood, the ICMP packets are sent more rapidly.
