Explanation:

- Afreena walks 8 km East from the start.

- She turns back and walks 13 km West.

- Position is now 5 km West from start.

- She turns left, walking 4 km South.

- She turns left again, moving 5 km East.

- Now she is 1 km West and 4 km South of the start.

- Finally, she turns left and walks 3 km North.

- New position is 1 km West and 1 km South.

- Calculate the straight-line distance.

- Apply Pythagoras: v(1² + 1²) = v2 ˜ 1.41 km

- Thus, closest option is Option:1, 3 km.
