Why each option
The 'redistribute bgp' command is the correct IOS syntax used under an IGP process to import BGP-learned routes into the IGP routing table.
The 'redistribute bgp [AS-number]' command, entered under the IGP routing process (such as OSPF or EIGRP), instructs the router to take routes learned via BGP and inject them into the IGP, making them available to internal routers that do not run BGP.
'redistribute static' imports routes that were manually configured as static routes into the IGP, not routes learned dynamically via BGP.
'redistribute static subnet' is not a valid Cisco IOS command for any route redistribution purpose.
'default-information originate' advertises a default route (0.0.0.0/0) into the IGP, not specific BGP-learned prefixes.
