D

Understanding the Answer
Let's break down why this is correct
Answer
When two charged plates are pulled apart, the voltage that can be applied across them usually stays the same, so the field inside is the voltage divided by the distance. Because the electric field is the voltage per unit length, making the plates farther apart makes the field weaker. Imagine a 10 V battery across the plates: if the plates are 1 cm apart the field is about 1 kV/m, but if they are 2 cm apart the field drops to about 0. 5 kV/m. Thus the primary effect of increasing the separation is a reduction in the electric field strength.
Detailed Explanation
Increasing the gap makes the same amount of charge act over a larger space. Other options are incorrect because Many think a wider gap makes the field stronger; Some believe the field stays the same no matter the distance.
