A school asks two teachers to verify digital examination results before publication. Why is this step necessary?

Answer and explanation

Correct answer: To ensure data accuracy

The governing concept is data quality assurance through verification. Digital systems can process results quickly, but incorrect marks, missing entries, or mismatched student records may also be published quickly if nobody checks them. Two-person verification helps detect such errors before release. Therefore, option A is correct; screen size, file colour, and internet speed do not improve the accuracy of examination data.
