Explanation:

To solve this, we analyze the context. The passage says the Braille system (invented by Louis Braille) is widely used today to help the blind read. "Benefited" means to be helpful or advantageous. "Impressed" is about making a strong impression, "exposed" is about revealing, and "challenged" is about presenting a challenge—none fit as well as "benefited" since the system helps the blind.

Answer:

D. benefited
