Answer:
b. Upstairs room
Explanation:
Family day care homes are prohibited in the room which are upstairs because, that is not suitable for old age people and small children as they do not feel safe to climb stairs.
As in old age the most common problem faced is that in legs, and knees specifically.
This certainly leads to avoiding the day care homes from upstairs. As small children will also not be able to climb properly and might fall, this is therefore avoided.
