Explanation:

- Option 1: Analysed

- This is the most appropriate choice. To "analyse" means to examine methodically and in detail. It fits well as the action required to understand and compare students' performance through their marks.

- Correct Answer

- Option 2: Questioned

- "Questioned" means to ask questions about something. This doesn't fit in the context of examining marks for performance comparison.

- Option 3: Inspected

- "Inspected" means to look at something closely. While somewhat applicable, it doesn't quite capture the systematic examination implied by "analysed."

- Option 4: Probed

- To "probe" means to explore or investigate thoroughly. It's not typically used for examining and comparing data like marks.
