The two correct statements about IPv6 prefixes are:

1. **FF00::/8 is used for IPv6 multicast.** - This is true, as the FF00::/8 prefix is designated for multicast addresses in IPv6.

2. **FE80::/10 is used for link-local unicast.** - This is also true, correct prefix for link-local addresses in IPv6 ranges from FE80:: to FEBF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF.

The other two statements are not correct:

- **FEC0::/10 is used for IPv6 broadcast.** - This is false because IPv6 does not use broadcast addressing; it uses multicast and other means for similar functionality.

- **FE80::/8 is used for link-local unicast.** - This is false because the correct prefix for link-local addresses is FE80::/10.

So the true statements are the first and the fourth: **FF00::/8 is used for IPv6 multicast** and **FE80::/10 is used for link-local unicast**.
