A. B. C. D.B.
To ensure that Ann's mobile device has enough power for day-long conferences where wall outlets may not be available, the technician should recommend a built-in battery case.
Option A, a wireless charging pad, may not be suitable for Ann's needs as it requires a power source, such as a USB port or wall outlet, to function. If there are no wall outlets available, Ann would not be able to charge her device with a wireless charging pad.
Option C, extra charging cords, would be helpful only if there are available wall outlets to charge from. In the absence of wall outlets, extra charging cords would not be of much help.
Option D, airplane mode, can be useful for conserving battery life but would not solve the issue of the device running out of power. It only disables the device's wireless communication, which is not suitable if Ann needs to receive important updates.
The built-in battery case, option B, is a case with a battery built into it that can provide additional power to the device. This is the best option for Ann, as it does not require a wall outlet or any external power source. The battery case can be charged separately and used to power the device throughout the day. This option ensures that Ann's device will have enough power to receive important updates throughout the conference day.
