I have a IPv4 packet which has encapsulated over IPv6. tunneling setup protocol is used. Now i want to check which options from IPv4 header are being used in a packet. What is the way to do that? How can I identify which options are being used?

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.
