An ASBR located inside an NSSA redistributes external routes into that area. Which OSPF LSA type will that ASBR originate within the NSSA?

An ASBR in an NSSA originates Type-7 LSAs to advertise external routes into that NSSA. These Type-7 LSAs are then translated into Type-5 LSAs by an ABR connecting the NSSA to the backbone area, allowing the external routes to be flooded throughout the rest of the OSPF domain. Type-5 LSAs are for external routes advertised into regular areas, not directly into NSSAs by the ASBR. Type-3 LSAs summarize routes between areas, and Type-1 LSAs describe the router's directly connected links and their states within a single area.
