Answer:
+ 14
Explanation:
18 protons make a positive 18 charge (+18)
4 electrons make a negative 4 charge (-4)
both combined give + 18 - 4 = + 14
The four neutrons don't carry net charge, so the addition of the electrons doesn' affect the net charge found above which still gives + 14.
A Car at the top of a hill.
It is because in that case, produce of mass and height is highest which is directly proportional to potential energy
In short, Your Answer would be Option A
Hope this helps!
