A smartphone user unsuccessfully attempts to open an email attachment that includes an unexpected overdue invoice. After that attempt, the user notices performance issues while using the mobile browser and other applications. The user restarts the smartphone, but the issue persists. Which of the following actions would most likely resolve the issue?

While forcing a shutdown and restart can temporarily resolve minor glitches or unresponsive applications, it does not address underlying software issues that might have been caused by the problematic email attachment. If the performance issues are due to deeper software corruption, this action would likely be ineffective.

Deleting the email may clean up the user’s inbox, but it does not resolve any performance issues that have already affected the device. If the root cause is related to software corruption triggered by the attachment, merely deleting the email will not restore the smartphone's functionality.

While uninstalling and reinstalling the mobile browser may fix browser-specific issues, it does not tackle potential system-wide problems that could have arisen after the email attachment attempt. The problem may not be isolated to just the browser, making this option less likely to resolve the overall performance issues.
