A.I. Explanation:

Option 1: "To provide suggestions and guidance about how to lift the image of Washington."

Explanation: The text states that the Commission of Fine Arts was established to enhance the image of Washington as an important international capital, focusing on dignity and beauty. This aligns directly with the purpose of providing suggestions and guidance to achieve that goal.

Option 2: "To assist presidents with deciding which art projects at Washington should be approved."

Explanation: This option misinterprets the role of the Commission. The text does not mention assisting presidents with project approvals; instead, it emphasizes the Commission's broader purpose of improving the city's image.

Option 3: "To create and display beautiful and dignified art works for the city of Washington."

Explanation: While the text discusses beauty and dignity, it does not state that the Commission is responsible for creating or displaying art. Its focus is on guiding public projects rather than directly producing art.

Option 4: "To organize and manage the art exhibitions and other events hosted in Washington."

Explanation: This option suggests a management role for exhibitions, which is not supported by the text. The Commission's purpose is centered on enhancing the city's image through guidance on public projects, not event management.
