The correct answer to this question is A. A parent goes to school instead of the child. The parent will get informed of all the information needed for the day and go home to teach the sick child. This policy differs from other countries. For example, in the United States, if a child is sick, the parent can make a phone call to the school, informing them of the absence.
After their return, they would be able to make up any work missed. For prolonged absences, the teachers and/or principal may make an exception that the student doesn't have to make up any missed work.
