In the five tests listed, which item specifies there are no keyboard traps?

• A. (2A) Pause, Stop, or Control Volume of Audio Content That Plays Automatically
• B. (2B) Pause, Stop, or Hide Moving, Blinking, or Scrolling Content
• C. (3A) No Flashing Content Is Present
• D. (4C) There Are No Keyboard Traps

Answer: (D)

Keyboard navigation is the focus here. A keyboard trap occurs when focus cannot be moved away from an element using keyboard input, leaving a user stuck inside a dialog, menu, or widget. The statement that there are no keyboard traps directly asserts that such a trap does not exist, meaning a keyboard user can tab through all interactive elements and exit or move on as needed. This directly matches the requirement of ensuring keyboard accessibility, making it the best choice. The other options address different accessibility concerns—automatic media controls, content that moves, and flashing content—not the ability to navigate with the keyboard or escape from a focused element.
