Accessibility impacts people positively in several ways, but the most direct option from your list is:
B. Improved access to consumer goods
When people have better access to consumer goods, it can lead to enhanced quality of life, as they can obtain essential items, services, and resources more easily. Improved access can support local economies, provide a wider range of products, and enable individuals to meet their needs more effectively.
While the other options can also have positive impacts, they are more indirect and may not relate specifically to the concept of accessibility in a way that directly enhances everyday life for individuals.
