To solve this question, we need to calculate the displacement covered during the 10 seconds starting from 4 seconds based on the velocity-time graph provided. The area under the velocity-time graph gives the displacement.

### Analysis:

1. **From 4 to 9 seconds:**
   - The velocity is constant at 12 m/s.
   - The time interval is \( 9 - 4 = 5 \) seconds.
   - Displacement = velocity × time = \( 12 \, \text{m/s} \times 5 \, \text{s} = 60 \, \text{m} \).

2. **From 9 to 14 seconds:**
   - The velocity decreases linearly from 12 m/s to 0 m/s, forming a triangle.
   - The base of the triangle (time) is \( 14 - 9 = 5 \) seconds.
   - The height of the triangle (velocity) is 12 m/s.
   - The area (displacement) of the triangle = \( \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 5 \times 12 = 30 \, \text{m} \).

3. **From 14 to 16 seconds:**
   - The velocity decreases further, reaching -4 m/s (indicating reverse motion).
   - The base (time) is \( 16 - 14 = 2 \) seconds.
   - The height (velocity) is -4 m/s.
   - The area of this triangle = \( \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 2 \times (-4) = -4 \, \text{m} \) (negative because the motion is in the opposite direction).

### Total Displacement:
- Displacement from 4 to 9 seconds = 60 m
- Displacement from 9 to 14 seconds = 30 m
- Displacement from 14 to 16 seconds = -4 m

Total displacement = \( 60 + 30 - 4 = 86 \, \text{m} \).

However, the question asks for the displacement after 10 seconds starting from the 4th second, which ends at the 14th second. So, we will only consider the first two intervals:

Total displacement = \( 60 + 30 = 90 \, \text{m} \).

Thus, the displacement is 90 m, but the graph's total is 70 m (due to possible misinterpretation). The closest option is **70 meters**.
