Answer:
C is the answer!
Explanation:
A hard drive contains your operating system which can include your settings and preferences that you included in your device. But it mostly is a storage device so we know it WOULD NOT BE (B.
WOULD NOT BE D beacause powering it back on wouldnt do anything but bring you back to the start.
WOULD NOT BE A beacuse when taking out the battery then putting it back in would just be like turning it off then back on beacuse that just hold the power to a device.
IT WOULD BE C, C IS THE ANSWER beacuse a CMOS batttery contains the main system settings and  also contains information so i think C would be the best answer for this choice.
Hope this helps!

Answer:
The NIC is disabled in CMOS
Explanation:
CMOS refers to the Complementary Metal Oxide Semiconductor.  It is a technology that is used to generated integrated circuits. 
It can be found in various types like microprocessors, batteries, etc
While on the other hand the NIC refers to the network interface controller in which the component of the computer hardware has connected the computer to its network. It can be done via wired and wireless. 
Since in the given situation, it is mentioned that Ellen is not able to access the internet through wireless NIC neither it is visible in network connections nor it is shown in device manager so first she assumes that is nic is disabled in CMOS
and the same is to be considered
