The CSS rule `body { font-size: 50%; }` sets the font size of the body element to 50% of its parent's font size.
The potential answers can be clarified as follows:
- **half the width of the screen**: This is incorrect because the font size is not related to the width of the screen.
- **half the default font size**: This is correct if the default font size is, for example, 16 pixels (which is the common default in many browsers). In that case, 50% would set the font size to 8 pixels (which is half of 16 pixels).
- **50 pixels**: This is incorrect because the rule doesn't specify an absolute font size like pixels, but a percentage of the parent element's font size.
- **size 50**: This is not a correct interpretation as it does not accurately describe how font sizes work in CSS; it does not convey a clear measurement.
So the accurate interpretation of the `body { font-size: 50%; }` rule is that it sets the font size to half of the parent element's font size, which is commonly understood to mean "half the default font size" if we are referring to the body of the document.
