Roads in urban areas are generally

a narrower and more compact

b unpaved and more compact

c rougher and more interesting

d wider and more interesting

D is the answer

Explanation:

Urban roads tend to be wider. Sometimes they are more interesting, but that does not always have to be the case. D

They are usually paved, especially in Canada and the United States. I have not seen very many urban roads that are not paved, even those of the edge of the urban areas. Not C. Not B either.

Few are narrow although there are exceptions. White Avenue in Edmonton Alberta is 4 lanes but it still seems narrow to me. It is very interesting however.  Not A

i think the answer is b.
