One Answer:

You can apply a Wireshark display filter of ip.hdr_len > 20 or ip.opt.type, which will isolate those packets that contain IPv4 options, and then expand the IPv4 protocol details within the packet details pane to reveal the packet details. You should see the "Options" listed, and you can expand those too if you like.
