Explanation:

- Srinija starts by walking 9 km west.

- She then turns south and walks 11 km.

- After that, she walks 13 km east.

- Finally, she moves 4 km west.

To find how far she is from her starting point, consider her end position:

- The net movement horizontally: \(9 \text{ km west} - 13 \text{ km east} + 4 \text{ km west} = 0 \text{ km}\) (She ends up in line with her starting point on the east-west axis).

- The net movement vertically: \(11 \text{ km south}\).

Thus, she is directly 11 km south of her starting point.

- Correct Option: 11 km

Correct Answer: Option 1 – 11 km
