What is the alternative notation for the IPv6 address
B514:82C3:0000:0000:0029:EC7A:0000:EC72?

A.
B514 : 82C3 : 0029 : EC7A : EC72

B.
B514 : 82C3 :: 0029 : EC7A : EC72

C.
B514 : 82C3 : 0029 :: EC7A : 0000 : EC72

D.
B514 : 82C3 :: 0029 : EC7A : 0 : EC72

Explanation:
There are two ways that an IPv6 address can be additionally compressed: compressing
leading zeros and substituting a group of consecutive zeros with a single double colon (::).
Both of these can be used in any number of combinations to notate the same address. It is
important to note that the double colon (::) can only be used once within a single IPv6
address notation. So, the extra 0’s can only be compressed once.
