What message needs to be input for the GPA data validation error alert?

The message that indicates "GPA must be between 2.5 and 4" is the most accurate for GPA data validation because it sets a standard for acceptable academic performance. Generally, a GPA on a standard scale ranges from 0 to 4.0, where a performance of 2.5 is often considered the minimum for passing or being in good academic standing at many institutions. This range helps to ensure that only those with a level of academic achievement that meets the specified criteria are considered valid.

In contrast, specifying a range that includes 0 to 5 would not align with standard GPA calculations, as most institutions do not utilize a scale extending beyond 4. Moreover, stating that a GPA must be below 4 fails to promote any meaningful academic standard and could result in confusion about what constitutes acceptable performance. Lastly, the option that only includes valid grades as 1.0 and 4.0 misrepresents the GPA scale entirely, as it does not account for the full range of possible GPAs or the increments that exist within that range. Hence, the preferred option accurately reflects common academic standards and expectations for GPA validation.
