No-Summaries makes this a totally stubby area. no summaries.

no-summaries—(Optional)
If configured in combination with the default-metric statement, a totally stubby area only allows routes internal to the area and advertises the default route into the area.
By default, when the no-summaries statement is configured, a Type 3 LSA is injected into the nonbackbone area.
So “B” is right.
