the answer is: c. preschoolers have problems with this type of coordination.
Option C is the correct one because preeschoolers are not developed enough yet to have that capacity.
At the age three to four, the child will try to color within the line but there won't be much success.
When they are around five years old, we can see coordination between the fingers and wrist, and they start to show what hand is going to be dominant. By the time they are six, all of this should be apparent, consistent and they should be capable of staying within the lines.
Teachers from a generation ago, did not knew about this and would pressure the kids to do something they were not ready for.
