Why would a child be sent home in Ellis Island?
If immigrants had any of the diseases proscribed by the immigration laws, or were too ill or feeble-minded to earn a living, they would be deported. Sick children age 12 or older were sent back to Europe alone and were released in the port from which they had come. So It seems A is the right anwser.
It was created so citizens will know the law, it was made so they could know it
