there is little demand for the indigenous dialects
B
the convergence of people from disparate regions results in the pressure of communication
C

D
they are made up of both rural and urban dwellers
Verified Correct Answer: D.
Grammar & Contextual Explanation
The passage explains that:
Rural dwellers tend to maintain their indigenous dialects due to limited movement.
Urban dwellers need a standard dialect to facilitate communication in a diverse environment.
Since a language community consists of both groups, its members naturally control at least two dialects, using them as needed in different social contexts.
