Answer:
A. career and educational opportunities are more common
Step-by-step explanation:
In the developed countries, the women have the same rights as the men for quite some time now. This meant that the women had the same opportunities in life as men, so naturally they embraced it and focused on it.
For starters, the women were allowed and encouraged to get educated, which immediately changed their lives and their perceptions, as well as their skills. Further, all of the jobs on the labor market opened up to the women, so the women started to work and build careers instead of sitting home and being housewives.
While this has had great effect on the social life, the economy, and the independence of the women, it had very negative effect on the demographic trends. Since the women became equal to men and have the same opportunities in life, they tend to delay getting married and are getting married much later. After they get married they delay having a child, so when they have one there is no time usually for another one. This has resulted in drastic drop in the birthrates and aging population.
