C. ARM technology

D. advanced microprocessors

A. Xcode libraries

Explanation:

We have to find a requirement for developing game applications on devices running Apple's iOS operating system. For that, I will evaluate each answer.

A. Xcode libraries

Xcode can be generally defined as a development kit or integrated development environment to facilitate the Apple software development. Apple use iOS operating system for its devices. To develop anything compatible with iOS, you generally have to code it using Xcode. Obviously, each development kit includes libraries for project to be built. Therefore, this option is correct.

B. Android Development Kit

Just like Xcode, Android Development Kit is used to build the software for android. It is pretty much comprehensible from its name. So, this option is false.

C. ARM technology and D. advanced microprocessors

These both options are related to hardware and available on both the devices. It is used for overall processing but these options are not that relevant to iOS operating system. Therefore, these options are false too.

So, Correct option is Xcode libraries.
