What does the noresize frame attribute do?

The correct answer is that the noresize frame attribute prevents resizing of frames. This attribute is used in conjunction with the <frame> element within a frameset. When the noresize attribute is specified, it indicates that the user should not be able to adjust the size of that specific frame by dragging its borders. This is useful for maintaining a fixed layout where frame dimensions must remain constant to ensure proper content display and functionality.

The other choices focus on attributes or behaviors that do not align with the noresize attribute's functionality. For example, the idea that it allows resizing is directly contradicted by its purpose. Similarly, automatic size adjustment and the creation of non-scrollable frames are unrelated to the resizing capability controlled by the noresize attribute. This attribute strictly deals with user interactions regarding frame dimensions.
