Which of the following is ordinal categorical data?

Explanation:
This question tests understanding of ordinal data versus nominal and numerical data. Ordinal categorical data are categories that have a natural order, but the gaps between categories aren’t assumed to be equal. The option with grades uses a clear order—higher grades are better and you can say A is higher than B is higher than C—so it fits the idea of ordered categories. The other options don’t have that feature: hair colour is a category with no inherent order, so it’s nominal; temperature in Celsius and weight in kilograms are numerical measurements, not categories, so they’re treated as quantitative data rather than categorical.
