Explanation / Answer

I think you mean compilation error, not complication. Anyways it is compilation error because the code goes from if to else if to else if to else if to else if and then stops. A correct code needs to have somewhere to end but the code snip never has an "else" statement to end the conditions. Thus a compilation error will occur. So a. is correct answer.
