Explanation:

- Let's analyze the statements:

- A$B means A is not smaller than B (A = B).

- B%F means B is not greater than F (B = F).

- F#D means F is neither greater nor equal to D (F < D).

- Now, let's evaluate the conclusions:

- Conclusion I: B#M - B is neither greater nor equal to M, which means B < M. The information given doesn't directly support this conclusion.

- Conclusion II: A%Y - A is not greater than Y, implying A = Y. The information given doesn't establish a direct relationship between A and Y.

- Conclusion III: Y@B - Y is neither smaller nor equal to B, meaning Y > B. This conclusion aligns with the derived statements since B = F < D, and Y@M*F means Y > F and F = M.

- Conclusion III holds based on the information provided.

- Option 3: Only III follows is the correct answer.
