C Correct answer
Explanation

Dalvik VM (the virtual machine in Android's runtime) executes files in .dex (Dalvik Executable) format. Java bytecode is converted to .dex format during the Android build process. The .dex format is optimized for memory-constrained devices and uses a different instruction set than standard Java bytecode. .txt, .dtx, and .dx are not executable formats for Dalvik VM.
