Answer:
C, decreasing population
Step-by-step explanation:
Many counties in Europe suffer from low birth rates due to limited number of children being born there. This in turn is due to high cost of living and the difficulty of finding a job. Many families struggle financially and they can afford one child only. Women delay having children because they want to establish themselves in their careers first.
Because of all this above, the demographic trend would be decreasing population, where the number of deaths outnumbers the number of annual births.
