You are using Wireshark to try and determine if a denial$-$of$-$service $($DDoS$)$ attack is happening on your network $(128\mathrm{.}28\mathrm{.}1\mathrm{.}1).$ You previously captured packets using the tcp$.$flags.syn$==1$ and tcp$.$flags.ack$==1$ filter, but only saw a few SYN$-$ACK packets. You have now changed the filter to tcp$.$flags.syn$==1$ and tcp$.$flags.ack$==0.$ After examining the Wireshark results shown in the image, which of the following is the best reason to conclude that a DDoS attack is happening?

Question $61$ options:

There are multiple SYN packets with different source addresses destined for $128\mathrm{.}28\mathrm{.}1\mathrm{.}1.$

There was a flood of SYN packets without a matching SYN$-$ACK packet.

The source address for all SYN packets is $198\mathrm{.}28\mathrm{.}1\mathrm{.}1.$

The Transmission Control Protocol shows the hex value of the SYN flag is $0$x$002.$
