Default IPV6 addresses how are they written?

Multiple choice quiz:

A) IPV6 addresses are 4 groups of 4 hexadecimal characters separated by colons.
B) IPV6 addresses are 6 groups of 4 hexadecimal characters separated by colons.
C) IPV6 addresses are 7 groups of 4 hexadecimal characters separated by colons.
D) IPV6 addresses are 8 groups of 4 hexadecimal characters separated by colons.

If you look at the current version of "Absolute OpenBSD" 2nd Edition (PDF), then
page 193 under "IPV6 Basics" says that B) is the correct answer.

If you go to the OpenBSD FAQ section 6.1, it suggests reading the
"Understanding IP Addressing" by 3COM.

http://openbsd.org/faq/faq6.html#Intro

http://www.scribd.com/doc/52483921/3...-IP-Addressing

And if you look on page 43 of the 3COM document you find
"Figure 36: Hexadecimal to Binary Conversion"
which clearly shows that C) is the correct answer.

However if one looks at either the FreeBSD FAQ or the NetBSD FAQ
or Wikipedia then D) is the correct answer.
