Answer
Option C is correct.
9 units.
Step-by-step explanation
To know this distance, we will move vertically and horizontally along the coordinates to know the real distance.
From car to cabana, it is a movement of 3 units downwards along the y-axis, then from cabana to the beach, it is a movement of 6 units to the right along the x-axis.
Total movement = 3 + 6 = 9 units.
Hope this Helps!!!
