Show answer and explanation
Correct answer: A
Explanation
The yellow exclamation mark in Device Manager indicates a driver or device issue. Since the problem began after a recent driver update, rolling back the driver is the best immediate action to revert to a stable version. This avoids further issues that might arise from reinstalling or updating the driver without fully diagnosing the cause of the problem.
- A. Correct.
Rolling back the printer driver to a previous version is the most appropriate step in this scenario since the issue started after a recent driver update. This action can revert the driver to a working version.
- B. Incorrect.
Disabling and re-enabling the device might refresh the device, but it won't address the underlying issue caused by a faulty driver update.
- C. Incorrect.
Uninstalling the device and restarting the computer might reinstall the same problematic driver, so it is not the best immediate solution in this scenario.
- D. Incorrect.
Updating the driver to the latest version could potentially fix the issue, but since the problem occurred after a driver update, rolling back is a safer first step.
