I would say this answer is wrong.
Correct answer would be
C. Route summarization for scalable routing and addressing design
Route Summarization
The design recommendations for summarizations are straightforward and include
-Using route summarization to scale routing designs.
-Designing addressing by using address blocks that can be summarized.
-Using default routing whenever possible. Route summarization is the ultimate route summarization, where all other routes are summarized in the default.

The C answer makes more sense even without special consideration. I’m not native English speaker, so the grammar confuses me here.
