Answer:
C. FEFE::2:0:0:1
Step-by-step explanation:
IP version 6 is the latest two IP address versions (with IP version 4 as the former) used in networking. It is a 128 bits address, divided into eight 16 bits hexadecimal values.
The address FEFE:0000:0000:0000:0002:0000:0000:0001 can be simplified with standard rules of simplifying IPv6 addresses.
The first rule says all consecutive zeros should be replaced with "::",
That is: FEFE::0002:0000:0000:0001.
The second rule states that all all leading zeros can be removed or excluded from the address,
That is: FEFE::2:0:0:1
