Explanation:

Initial Movement:
- Rina walks 18m towards west.
- This is her starting point.

First Turn:
- Rina turns to her right and walks 18m.
- She has now moved 18m towards the north.

Second Turn:
- Rina turns to her left and walks 13m.
- She has now moved 13m towards the west.

Final Turn:
- Rina turns to her left again and walks 18m.
- She has now moved 18m towards the south.

Calculating Shortest Distance:
- Rina has formed a right-angled triangle with sides of 18m, 13m, and 18m.
- We can use Pythagoras' theorem to find the shortest distance between her starting point and the new position.
- Shortest distance = √(13^2 + 18^2) = √(169 + 324) = √493 ≈ 22.21m
Therefore, the correct answer is option 'D', 31m.
