A public notice provides only a QR code and no alternative text. What is the main accessibility problem?

Answer and explanation

Correct answer: People without smart devices may not access the message

The governing concept is inclusive communication: important public information should be available through more than one accessible channel. A QR code requires a suitable device, connectivity, and the ability to scan it; people lacking these resources may be excluded. Therefore option B identifies the main problem. Formal wording, the label of the code, and feedback speed do not explain the access barrier described.
