An IPv4 packet has arrived with the first 8 bits being 01000010 The receiver discards the packet because the first 4 bits represent version IPV4.
and another 4 bits represent header length (/ 4) which should range between 20 to 60 bytes. Here 0010 represents header length, is equal to 2 * 4 = 8. So, the receiver will reject the packet.
