• C. Headings should be replaced by paragraphs.
• D. Each heading is visually identifiable as a heading, and also programmatically determinable.

Answer: (D)

Headings must be visually identifiable and programmatically determinable. This balance lets everyone grasp the page structure quickly: sighted users see where sections start, while assistive technologies can expose a document outline and enable jumping between sections. The right approach is to mark headings with semantic markup—like proper heading elements or equivalent ARIA roles—so they are recognizable to users and detectable by screen readers. If headings are only styled as bold or large text without semantic markup, their structural role is hidden from assistive tech, hindering navigation. Replacing headings with paragraphs or omitting them removes the navigation anchors that many users rely on. So, the emphasis is on headings that are both easy to spot visually and easy to identify in the underlying markup.
