Which of the following curves represent electrostatic field lines correctly?

Options

A.
B.
C.
D.

Explanation

To determine which of the given curves represents electrostatic field lines correctly, we need to analyze the properties of electric field lines and evaluate each option based on these properties.

### Step-by-Step Solution:

1. **Understanding Electric Field Lines**:
- Electric field lines represent the direction and strength of the electric field created by electric charges.
- Key properties of electric field lines include:
- They originate from positive charges and terminate at negative charges.
- They never intersect each other.
- They are perpendicular to the surface of conductors in electrostatic equilibrium.
- They do not form closed loops.

2. **Analyzing Each Option**:
- **Option A**: Electric field lines are emerging from positive to negative but intersect each other.
- **Evaluation**: This option is incorrect because electric field lines should never intersect.

- **Option B**: Electric field lines are directed outwards from a conductor, but the angle between the surface and the field lines is not 90 degrees.
- **Evaluation**: This option is also incorrect because electric field lines should be perpendicular to the surface of a conductor.

- **Option C**: Electric field lines are directed radially outwards from a positive charge, are perpendicular to the surface, and do not intersect.
- **Evaluation**: This option is correct. The lines are diverging away from each other, indicating repulsion between like charges.

- **Option D**: Electric field lines are forming closed loops.
- **Evaluation**: This option is incorrect because electric field lines do not form closed loops.

3. **Conclusion**:
- Based on the analysis, **Option C** is the correct representation of electrostatic field lines.

### Final Answer:
**Option C** represents the electrostatic field lines correctly.
