A Correct answer
Explanation

Java varargs syntax requires the varargs parameter to be the LAST parameter. Option A follows this: int x, int... args (x is fixed, args is varargs at end). Option B is invalid: int... args, int x (varargs cannot be followed by other parameters). Option C is missing the varargs syntax (three dots). Option D has incorrect placement and syntax.
