The code you provided is a simple quiz application that displays a question and multiple choice options. However, it has a couple of issues that need to be fixed:

1. You have defined the `questions` array with only one question object. It's better to have multiple questions in the array to make the quiz more interesting.

2. In the `showQuestion()` function, you are trying to access the `nextSibling` property of the option elements to set the text content. This is not the correct way to update the label text. Instead, you should set the `textContent` of the labels directly.

3. The `checkAnswer()` function is missing the logic to handle the case when no option is selected. You should include a check for this scenario and prompt the user to select an answer.

4. The `onclick` attribute value of the "Check Answer" button is missing in the initial code snippet. It has been added back to call the `checkAnswer()` function.

To address these issues, you can make the following fixes in the code:
- Add more question objects to the `questions` array.
- Update the `showQuestion()` function to set the text content of the labels directly.
- Modify the `checkAnswer()` function to handle the case when no option is selected.
- Include the `onclick` attribute value for the "Check Answer" button to call the `checkAnswer()` function.

After making these fixes, the quiz application should work correctly and provide a better user experience.
