Which IPv6 address block is intended for private use within an organization?

Explanation:
IPv6 private-use addresses are Unique Local Addresses, designed for internal networks and not routable on the public Internet. The block FC00::/7 is reserved for ULAs, which lets an organization have internally unique addresses. In practice, many networks use the FD00::/8 portion for their private addressing. The other options serve different purposes: Fe80::/10 is link-local, meant for the local network link only; ::1/128 is the loopback address used to refer to the local host; and 2001::/32 is a global unicast space used on the public Internet.
