Hi Amit,
No D is not 'explicitly' stated.
The first half is (birth rate declining), the second half (population aging) is a priori a conclusion to that.
As ever - just answer the question and move on. Don't worry about anything else. This question asks for 'indicates' - D is clearly indicated, so move on.
GMAT is hard enough as it is without worrying about hypotheticals.
