ALT text in newsletter images provides which of the following?

• A. It improves image resolution
• B. It is required for all images
• C. It increases load time
• D. It provides a text description for accessibility and can aid SEO, and helps when images are blocked

Answer: (D)

ALT text is a textual description of an image that serves two main purposes: helping accessibility and aiding understanding for search engines. For people who use screen readers, the alt text communicates what the image shows, so they can grasp the content even if they can’t see it. It also acts as a fallback when images don’t load, giving users context about what was supposed to appear. Additionally, search engines use alt text to interpret image content, which can help with indexing and potentially improve SEO. That’s why the best choice describes a text description for accessibility and SEO, and notes its usefulness when images are blocked. The other options miss the core function: it doesn’t change image resolution, it’s not strictly required for every image (decorative images often have empty alt text), and it doesn’t meaningfully increase load time.
