Final answer:
The primary traveling aids for a blind person are a white cane or a trained guide dog. Sidewalk ramps and Braille signs are accommodations and forms of accessibility required by the ADA for people with disabilities. The correct option is A) A white cane or a wheelchair
Step-by-step explanation:
The primary traveling aids for a blind person include a white cane or a trained guide dog. These tools provide independence and assist with mobility and navigation in various environments. A white cane helps detect obstacles and changes in the walking surface, while a trained guide dog can lead a person around obstacles and through crowds.
To address the reference question provided, sidewalk ramps and Braille signs are not disabilities. They are, in fact, forms of accommodation and accessibility for people with disabilities, as required by the Americans with Disabilities Act (ADA). These features make public spaces more accessible for people who have visual or mobility impairments. Therefore, the correct answer would be d. both b and c, as these are accommodations required by the ADA and forms of accessibility for people with disabilities. So, the correct option is A) A white cane or a wheelchair
