D. Statement-1 is False, Statement-2 is True

Answer

To solve the problem, we need to analyze both statements provided in the question:

**Statement 1**: In a region of space, both electric and magnetic fields act in the same direction. When a charged particle is projected parallel to the fields, it moves undeviated.

**Statement 2**: Here, the net force on the particle is not zero.

### Step-by-Step Solution:

1. **Understanding the Fields**:
- We have both electric field (E) and magnetic field (B) acting in the same direction.
- A charged particle (with charge \( q \)) is projected parallel to these fields.

2. **Forces Acting on the Charged Particle**:
- The force acting on a charged particle due to the electric field is given by:
\[ F_E = qE \]
- The force acting on the charged particle due to the magnetic field is given by:
\[ F_B = q(\vec{v} \times \vec{B}) \]
- Since the particle is moving parallel to the direction of the magnetic field, the angle between the velocity vector \( \vec{v} \) and the magnetic field \( \vec{B} \) is 0 degrees. Thus, the magnetic force becomes:
\[ F_B = qvB \sin(0) = 0 \]
- Therefore, the magnetic force \( F_B \) is zero.

3. **Net Force on the Particle**:
- The only force acting on the particle is the electric force \( F_E = qE \).
- Since \( F_B = 0 \), the net force \( F_{net} \) on the particle is:
\[ F_{net} = F_E + F_B = qE + 0 = qE \]
- Thus, the net force is not zero as long as \( q \) and \( E \) are not zero.

4. **Motion of the Charged Particle**:
- The charged particle experiences a force \( F_E \) in the direction of the electric field.
- Since there is no magnetic force acting on it, the particle will continue to move in a straight line in the direction of the electric field without deviation.

5. **Conclusion**:
- **Statement 1** is correct because the charged particle moves undeviated due to the absence of magnetic force.
- **Statement 2** is also correct because there is a net force acting on the particle due to the electric field.
- However, **Statement 2** does not correctly explain **Statement 1** because the reason for the undeviated motion is the absence of magnetic force, not just the presence of electric force.

### Final Answer:
- **Statement 1**: True
- **Statement 2**: True
- **Statement 2 is not a correct explanation for Statement 1**.
