The correct answers are:
A. Requires one parent to give up work for some time period - Stay at home parent
This would be a disadvantage as there would be only one source of income coming in while one parent has to give up work for some time.
B. May lead to disagreements about parenting styles - Family member
This would be a disadvantage as it does not help having family members disagreeing and voicing unwanted opinions while trying to raise a child.
C. May lead to difficulties in finding the right person for the family - Private child care
This would be a disadvantage as it can be hard to find someone you trust to look after your child when you have to return back to work.
D. Includes less individual attention for the child - Day care
This would be a disadvantage as each child will only receive a certain amount of care and attention and this might upset the child.
