Intra-Area-Prefix-LSA (Type 9) is used in OSPFv3 to carry IPv6 prefix information for a router or network and is flooded within the area.
Link-LSA (Type 8) is only sent on the local link and is not flooded throughout the area.
Inter-Area-Prefix-LSA (Type 3) and Inter-Area-Router-LSA (Type 4) are also flooded within an area but originate from ABRs, typically for cross-area route advertisement.
That said, Intra-Area-Prefix-LSA is specifically flooded within an area, matching the context of the question directly.
“Intra-Area-Prefix-LSAs are flooded within the area and advertise the IPv6 prefixes associated with router and network LSAs.”
