Let's analyze and solve this problem step-by-step:

We are given a number line with points labeled \( C, A, E, D, B \), and we need to match the points to the expressions provided in the options. Each expression involves square roots, so we will evaluate each one and place it on the number line to see if it corresponds with the given positions.

### Approximate Values:
1. \( \sqrt{2} \approx 1.414 \)
2. \( \sqrt{3} \approx 1.732 \)
3. \( \sqrt{8} \approx 2.828 \)
4. \( \sqrt{10} \approx 3.162 \)
5. \( \sqrt{12} \approx 3.464 \)

### Evaluate each expression:

- **(a) \( A = -\sqrt{8} \)**: 
  - \( -\sqrt{8} \approx -2.828 \), which is close to -3. This matches the position of \( A \) on the number line (near -3).

- **(b) \( B = 3\sqrt{2} \)**:
  - \( 3\sqrt{2} = 3 \times 1.414 \approx 4.242 \), which is slightly above 4. This does not match the position of \( B \), which is at 6 on the number line.

- **(c) \( C = -\sqrt{10} \)**:
  - \( -\sqrt{10} \approx -3.162 \), which is close to -3. This matches the position of \( C \), which is also near -3.

- **(d) \( D = \sqrt{12} \)**:
  - \( \sqrt{12} \approx 3.464 \), which is close to 3.5. This corresponds well with the position of \( D \), which is marked at 4 on the number line.

- **(e) \( E = -\sqrt{3} \)**:
  - \( -\sqrt{3} \approx -1.732 \), which is between -1 and -2. This does not match the position of \( E \), which is positive (near 1) on the number line.

### Conclusion:
The accurately placed values are:
- **(a) \( A = -\sqrt{8} \)**
- **(c) \( C = -\sqrt{10} \)**
- **(d) \( D = \sqrt{12} \)**
