Achild’s earliest ideas of right and wrong are taught in a-fixed expenses b-an emergency c-the school d-the home i say d but ? ?

All of the above are correct. They depend on the child's exposure. For example, if the child is neglected at home, D is incorrect. If the child does not go to preschool/kindergarten for whatever reason, then C is incorrect. If no emergencies happened during the child's early growth, then B is incorrect. I would go with A because children are taught wrong from right with time and with examples over time, hence fixed-expenses. 

I hope I was of help.
