## Multiple Choice Questions

You can create interactive Multiple Choice Questions (MCQ) by combining the Multi-line format with standard Markdown checklists.
Simply add a checklist on the front side of the card, marking the correct answer(s) with `[x]`.

```markdown
What is the capital of France?
- [ ] London
- [x] Paris
- [ ] Berlin
?
Paris is the capital of France.
```

!!! note "Displayed when reviewed"

<div class="grid" markdown>

!!! tip "Card Front"

What is the capital of France?<br/><br/>
🔘 London<br/>
🔘 Paris<br/>
🔘 Berlin<br/>

!!! tip "Card Back"

The correct option (`Paris`) is highlighted in green. If you selected a wrong option, it will be highlighted in red.<br/><br/>
Paris is the capital of France.
