I think this is a language problem, I suspect that the person posing the question was not a native English speaker.

The fact is that IL code is input to the JIT and native code is the output.

Some people read "3. The instructions compiled by JIT" as "the input to JIT" and some read it as "the output of JIT".

The problem is the use of the verb "compiled". The subject of this verb should be the input.

Eg: "C# is compiled by the compiler".

This means that option 3 is correct, but I would suggest that 3 and 4 should be re-written.

One of the correct option is 4th and not the 3rd. JIT compilation converts MSIL to native code on demand at application run time.

Sorry guys, but 1, 2 and 4 are correct.

3 is incorrect because JIT compiles IL into native code it does not compile native code.

IL code converted into native code trough JIT compiler. Option 3 is wrong.
