A mobile device user has tried to install a new app numerous times without success. She has closed all unused apps, disabled live wallpapers, and restarted the device in an attempt to get the app to install. Which of the following steps should the user take next?
A. Back up all user data and perform a factory reset.
B. Check for sufficient available storage space.
C. Disable full device encryption.
D. Generate a new public key.

The correct answer is B. Check for sufficient available storage space.  

Explanation:

One of the factors that can cause it is not possible to install a new app is insufficient storage as space in the mobile device is needed to save the app. This can be easily solved either by deleting apps and other content or expanding the memory available through a Micro SD card. Also, before attempting any major procedure such as a complete reset it is important to check the storage space availability. In this context, the user should check for sufficient available storage space (option B) because this might be the cause of the issue she is experiencing; also, this is a basic step before considering others such as performing a factory reset.
