Careful! IPv6 only uses hexadecimal characters (0-9, A-F). Option D may look correct in its formatting (only one set of :: to substitute for all-zero octets), but WXYZ are invalid hexadecimal characters.

Option C may look correct...

Hex digits range from 0-9 and A-F hence WXYZ are not included.

wxyz who it can be hexadecimal is from a to f

A is incorrect as it has :: twice B is incorrect as it only has 6 octets and no :: C is incorrect as it has characters that are not hexadecimal values D is correct
