Answer:
B. Use cross-platform tools to write code that will translate the existing Android app code into different native formats.
Explanation:
Cross-platform development involves building applications or programs to run on more than one Operating System (OS). It cuts across different platforms and devices, granting access to users no matter the device they are using. Remaining relevant in software development requires mastering tools to achieve this.
For Shania to make an old app designed for Android available on other platforms, she has to use cross-platform development tools that will help her to translate the code written for Android to other formats. Such tools include Adobe PhoneGap, Corona, Appcelerator among others.
