The capacitance of a parallel plate capacitor is a property that measures how much electric charge it can store. The capacitance depends on the area of the plates, the distance between them, and the material between them. The formula for the capacitance of a parallel plate capacitor is: C = kϵ0A/d, where C is the capacitance, k is the relative permittivity of the material, ϵ0 is the permittivity of free space, A is the area of the plates, and d is the distance between the plates1.

From this formula, we can see that decreasing the distance between the plates (d) will increase the capacitance (C) and increasing the area of the plates overlap (A) will also increase the capacitance. So, option I and option III are correct. Therefore, the correct answer is A. I and III only
