Option A -> Invalid data type error : Integer
Option B -> the ' ) ' is missing in this -> so throws error in this -> otherwise it will give o/p -> 6
Option C,D -> both gives same o/p -> 6
if in function calling string is sent as '8' then all 3 options B,C,D -> gives answer -> 270 which is incorrect
So if we consider the preference then option C should be considered correct. but it doesn't mean B,D are incorrect.

B, because: (Number(num)+10)/3
