Explanation

Option A (2002:c0a8:101::42) is valid - it's a 6to4 address with proper format. Option B (2003:dead:beef:4dad:23:46:bb:101) is valid - it's a full 8-hextet address. Option C (::) is valid - it's the unspecified address. Option D (2000::) is valid - it's a prefix notation. Option F is INVALID because it uses :: twice (2001:3452::4952:2837::), which is not allowed in IPv6 notation. Therefore E (Both A and B) is correct because both A and B are valid IPv6 addresses.
