Answer: B. receive the full support ordered by the court less than half of the time.
Explanation:
When the court awards custody to a parent, they order the other parent to contribute support to the upkeep of the child/children so that the entire burden does not fall on the custodial parent.
While one would expect that the other parent would support their child, a report by the U.S. Census Bureau found that custodial parents receive the full support they are to receive only about 43.5% of the time which is less than half of the time.
