Which of the following is a task a guide dog for a visually impaired person might perform?

• A. Guiding along safe paths.
• B. Guarding the home.
• C. Fetching the mail.
• D. Sleeping through the day.

Answer: (A)

Guiding along safe paths is the primary function of a guide dog for someone who is visually impaired. These dogs are trained to navigate environments, avoid obstacles, and steer their handler along routes that stay clear of hazards, helping with confidence and independence in daily movement. The other options don’t fit this role: guarding the home is a protection task, which isn’t part of mobility assistance; fetching the mail is not a core mobility task and isn’t typically included in guide-dog training; sleeping through the day would render the dog ineffective in assisting the handler when help is needed. So, the best answer is guiding along safe paths.
