D

Step 1: Understand the nature of electric lines of force.
Electric lines of force, also known as electric field lines, are conceptual tools used to visualize electric fields.
Step 2: Analyze each statement.
- **Option A**: True, electric lines originate from positive charges and terminate at negative charges. This represents the direction of the electric field.
- **Option B**: True, electric field lines do not intersect each other at a point. If they did, it would imply that the electric field has two different directions at that point, which is impossible.
- **Option C**: True, the electric field lines have a similar pattern for a point charge and a uniformly charged sphere. Both exhibit radial symmetry.
- **Option D**: False, electric lines of force do not have a physical existence; they are an abstract representation of the field.
Therefore, the wrong statement is option D.
