The Android Runtime (ART) uses the Just in Time (JIT) compiler. Here's a step-by-step explanation:

1. Android originally used the Dalvik Virtual Machine (DVM) which uses a Just-in-Time (JIT) compiler to compile the bytecode into machine code each time an app is launched.

2. However, starting from Android 4.4, Google introduced a new runtime called Android Runtime (ART) which uses a combination of ahead-of-time (AOT) compilation, just-in-time (JIT) compilation, and profile-guided compilation.

3. When an app is installed, ART compiles the app's bytecode into machine code (AOT compilation). This increases the app's performance.

4. When the app is running, ART uses the JIT compiler for parts of the code that are frequently executed. This further optimizes the app's performance.

5. Finally, ART uses profile-guided compilation, which means it monitors the app's execution, identifies hot methods (methods that are frequently executed), and compiles those methods into machine code for faster execution.

6. Therefore, among the options provided, Android Runtime (ART) uses the Just in Time (JIT) compiler.
