Answer:
The correct answer is d. Child-free couples experience a decline in marital satisfaction over time
Step-by-step explanation:
Having children is scary for many reasons: money, time, capacity, happy life as a couple.
On average, couples' satisfaction with their marriage decreases during the first years of marriage and, if the decline is particularly pronounced, they can continue the divorce.
For more than 30 years, researchers have studied how having a child affects a marriage, and the results are conclusive: the relationship between the spouses suffers once the children arrive.
