answer is A)
The amount of change held by a teacher at the end of each day for a year.

A is probably near normal (the teacher cant have negative cents in her/his pocket).
On the property taxes, it is impossible to say. For instance, what if there are 15 units, 5 of the small house, 5 of the medium house size, and 5 of the largest house size. That will not give a normal distribution.
The amount of pocket money held by each student will not give a normal distribution either.
