According to United Nations statistics, by the year 2030, more than 60 percent of the world population will be urban, up from 30 percent in 1950. Unlike the population growth in developed nations, the birth rate in less developed nations is high, meaning that the cities will continue to grow even as migration slows from the rural areas. Megacities such as New York, on the other hand, have populations that have leveled off over time.
Which new information, if true, might challenge the author's contention that certain cities will continue to grow despite a slowing of migration from the countryside?
(A) Scientists are creating news strains of rice and wheat that require far less in the way of hands-on care.
(B) The number of people living below the poverty level will climb in less developed and developed nations.
(C) Inflationary trends in heating oil and gasoline prices will limit most people's discretionary spending.
(D) New methods of birth control will limit the population explosion in the developing world.
(E) Demographers foresee ecological overload, homelessness, and infrastructure strained to the breaking point.

it all boils down to D AND E even though is a valid reason of why the urban population for that matter rural population will also diminish however D is something that directly provides evidence of why the urban population will dimish we have to go for this less appealling answer
