Correct answer
65 km towards south
Why this answer is correct
The logic followed here is:
Given:
Ravindra starts from Point Y (0, 0)
18 km North
Right turn → 45 km East
Right turn → 42 km South
Right turn → 26 km West
Right turn → 89 km North
Left turn → 19 km West
So, To return to Point Y, Ravindra must move 65 km South.
Hence, the correct answer is Option 4.
