According to the Apple Device Support Reference Materials, the three troubleshooting steps that you should try to resolve the issue of iPad not charging are:
* Force restart the iPad. This can help clear any software glitches that may prevent the iPad from recognizing the power source or charging properly 1 2 . The steps to force restart the iPad depend on whether it has a Home button or not 1 .
* Make sure that the device isn't too hot or too cold. Extreme temperatures can affect the battery performance and charging ability of the iPad 1 3 . The iPad should be kept within the acceptable operating temperatures of 0° to 35° C (32° to 95° F) 3 .
* Try charging with a different power adapter and cable. The power adapter and cable may be damaged or incompatible with the iPad, causing the charging issue 1 4 . It is recommended to use the original Apple power adapter and cable that came with the iPad, or other Apple-certified accessories 4 .
The other two options, D and E, are not relevant or helpful for resolving the charging issue. Backing up the device and erasing all content and settings may be useful for other issues, such as storage or performance problems, but not for charging problems 5 . Enabling Optimized Battery Charging is a feature that helps extend the battery lifespan by reducing the time that the iPad spends fully charged. It does not affect the charging speed or ability of the iPad.

FileVault is a feature that encrypts the data on your Mac's startup disk, making it more secure. To unlock your Mac, you need to enter your account password or a recovery key. A recovery key is a 28-character code that is generated when you turn on FileVault. You can choose to store it in iCloud or write it down and keep it in a safe place. An iCloud account and password can also be used to reset your FileVault password, if you enabled this option when you turned on FileVault. The other options, authenticator app, using a trusted device, and SMS verification code, are not valid ways to reset a FileVault password on a Mac. References

System Information > Hardware is the place where you can check to see if your podcast mic is properly connected to your Mac. System Information is an app that shows detailed information about your Mac hardware, software, and network. You can access System Information from the Utilities folder in the Applications folder, or by choosing About This Mac from the Apple menu and clicking System Report. Under the Hardware section, you can find information about your audio devices, such as the manufacturer, model, and connection type. If your podcast mic is connected to your Mac, it should appear under the Audio section. If it does not appear, you may need to troubleshoot the connection or try a different port or cable 1 2

Personal Hotspot depends on support from the user's wireless carrier and cellular service plan. Apple specifically states that if Personal Hotspot cannot be found or turned on, the user should confirm that the wireless carrier has enabled the feature and that the wireless plan supports it. Therefore, option A is correct.
Personal Hotspot does not require a 5G connection; it can operate with supported cellular data services on other network generations. Low Power Mode does not normally remove the Personal Hotspot option from Settings, and Wi-Fi Assist controls the use of cellular data when Wi-Fi connectivity is poor rather than determining whether Personal Hotspot exists. Carrier provisioning and plan eligibility are therefore the most relevant reasons that the Personal Hotspot setting might be unavailable.
