What is the role of the JIT compiler in .NET?
Correct answer D. It converts CIL into native machine code when methods are first called at run time
Explanation
JIT stands for just-in-time. When a method is invoked for the first time, the CLR's JIT compiler translates its CIL into native instructions for the current processor and caches the result for later calls. Turning C# into CIL is the job of the C# compiler (Roslyn) at build time, and freeing unused objects is the garbage collector's task.
