there must be two answers to this question
B – no-summaries—(Optional) Prevents the ABR from advertising summary routes into the stub area by converting the stub area into a totally stubby area.

You can convert area 0.0.0.3 to a totally stubby area by configuring the ABR to only advertise and allow the default route to enter into the area. External routes and destinations to other areas are no longer summarized or allowed into a totally stubby area.
FYI:
default-lsa—Configures the ABR to generate a default route into the NSSA
