Steps to solve the problem:

1. Calculate the distance walked in each direction:
- Mukesh walks 8 km towards the north.
- Then, he takes a 90° turn in the anti-clockwise direction and walks 10 km.
- Finally, he takes a right turn and walks 16 km.

2. Calculate the total distance walked:
- Total distance = 8 km + 10 km + 16 km = 34 km

3. Calculate the distance between the final and starting point:
- To find the distance between the final and starting point, we need to find the displacement.
- Displacement is the shortest distance between the final and starting point.
- Displacement = √(8^2 + 10^2) = √(64 + 100) = √164 ≈ 12.81 km

4. Answer:
- Therefore, the distance between the final and starting point is approximately 12.81 km.
- The closest option is 26 km (option D).
