Step-by-step explanation:
Sidewalk ramps and Braille signs are examples of accommodations required by the Americans with Disabilities Act (ADA) and forms of accessibility for people with disabilities. The ADA is a federal law that prohibits discrimination against individuals with disabilities and requires businesses and public entities to make reasonable accommodations to ensure accessibility.
For example, sidewalk ramps help individuals using wheelchairs or mobility devices to access sidewalks easily, and Braille signs provide information to individuals with visual impairments. These accommodations and accessibility measures promote inclusivity and equal access for people with disabilities.
Therefore, the correct answer is d. both b and c.
