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

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

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

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.

JIT converts MSIL into machine language.

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.

MSIL code is given input to the CLR. JIT compiles MSIL code.

Agree with Sandy. JIT compiles IL code, and not native code. The code JIT compiles to is native code.

Option 3 is wrong and option 4 is correct.. 100% sure.
So the correct options overhere are: 1, 2, & 4
So the correct options overhere are: 1, 2, & 4

@Ashutosh.
Only either 3 or 4 can be correct they both together can't be correct.
