The diagram shows two metal plates connected to a constant high voltage. Which graph shows the variation of the electric field strength E midway between the two plates as the distance d between the two plates is increased?

1. AGraph A: E decreases as d increases (inverse curve)
2. BGraph B: E constant as d increases
3. CGraph C: E increases as d increases (upward curve)
4. DGraph D: E decreases linearly as d increases
