The answer would be plant because the foliage is a part of the plant. They are related.
The three services offered by school health services are all
free of cost. These services include free emergency care, maintaining a healthy
sanitary school environment and imparting proper health education. Every school
health service should have a complete system in place to take care of any
emergency health related situation that might occur. The healthy and proper sanitation
system keeps away several diseases from attacking the children. The students
should also be made aware of issues that are unhealthy and should be avoided.
I believe the correct answer is principles. Hope this helps! :)
