Kirti starts from point A and walks 1 km towards east.
She takes a right turn and walks 2 km.
She then takes a left turn and walks 3 km.
She takes a right turn and walks 4 km.
She takes a left turn and walks 5 km.
She takes a final left turn and walks 6 km to reach a point B.
Based on the given conditions, we get the direction distance diagram as follows:
Therefore, we see that in order to go from Point B to Point A again, she has to walk (1+3+5) = 9 km towards the West.
Hence, the correct answer is "Option 1".
