B. If both Statement-I and Statement-II are true but Statement-II is not the correct explanation of Statement -I.
C. If Statement -I is true but Statement-II is false
D. If Statement-I is false but Statement -II is true

Answer

To analyze the given statements regarding electric lines, we will evaluate each statement step by step.

### Step 1: Evaluate Statement I
**Statement I:** Electric lines are always straight and continuous.

- **Explanation:** Electric field lines represent the direction of the electric field due to charges. These lines are drawn from positive charges to negative charges. In the case of a uniform electric field (such as between two parallel plates), the lines are indeed straight and parallel. However, in the vicinity of a point charge, the electric field lines are radial and curved. Importantly, electric field lines never intersect and are continuous, meaning they do not have breaks. Therefore, this statement can be considered **true** in the context of electric field representation.

### Step 2: Evaluate Statement II
**Statement II:** Electric lines represent a velocity field.

- **Explanation:** Electric field lines do not represent a velocity field. Instead, they indicate the direction and strength of the electric field at various points in space. The tangent to the electric field line at any point gives the direction of the electric field, not the velocity of a particle. Velocity fields are typically associated with fluid dynamics and motion, which is a different concept. Thus, this statement is **false**.

### Conclusion
- **Statement I is true.**
- **Statement II is false.**

Based on the evaluation of the statements, the correct conclusion is that Statement I is true and Statement II is false.

### Final Answer:
The correct option is that Statement I is true and Statement II is false.
