B Correct answer
Explanation

IPv6 addresses are 128 bits long, compared to IPv4's 32 bits. This massive increase (2^128 possible addresses) was necessary to address the IPv4 address exhaustion problem. 64 bits was considered but insufficient, 32 bits is IPv4, and 16 bits is far too small for global addressing.
