any help ??
Quite bad question since no prefix lenghts are specified.
However, an address ending with 0 or :: is a Subnet ID and so not a valid IP address.
A) :: is usually used as default IP, as ::/0. Could be correct
B) abbreviation of 0:0:0:0:192:168:0:1, a valid IPv6 address
C) ends with ::, representing a prefix (subnet ID). 2000::/3 reserved as global unicast
addresses.
D) ends with ::, representing a prefix (subnet ID)
E and F) valid IPv6 addresses.
First 2 and last 2
If it ends with (:: ), then it is prefix / subnet ID, therefore invalid
