Option 3 is correct. Because JIT is a part of CLR(VES) which converts IL code into machine code gradually during execution of program.

A machine code is also known as native code. So option 4 is wrong.

JIT converts MSIL into machine language.

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.
