A negatively charged balloon sticks to a wooden door. However, an uncharged balloon does not stick to a wooden door. What is the nature of the charge on the wooden door?
A. Electrically neutral
B. Positively charged
C. Conductor
D. Lacking protons
I am thinking it is A or B?

3. Its Definitely A.
Electrically neutral.
The door was neutral until the balloon came.
It is obviously neutral when the balloon is uncharged.
