Consider the below code and choose the correct output: class Adder { static int add (int a, int b) { return a + b; } static int add (int a, int b, int c) { return a + b + c; } } public class TestAdder{ public static void main(String[] args) { System.out.println( Adder.add (12, 12)); } } Select one: O a. Compilation error O b. 12 O c. 1212 O d. 24
