Correct answer: A. distance
Explanation: A dipole is a pair of equal opposite charges a short distance apart.
Field lines always point from positive to negative charge, are denser where the field is stronger, and never cross; an isolated positive charge has lines radiating symmetrically outward, while a dipole's lines curve from the positive to the negative charge.
