Explanation / Answer

Answers:

double sum = addition(4.2, 3.7); will call d option: double addition(double x, double y)

int sum = addition (4.2, 3); does not have valid method that will return a int.

int sum = addition (3, 5); will call a option: int addition (int x, int y)

double sum = addition (4.2, 3.7, 5.3, 9.4); does not have valid method definition. Miss matching the arguements.

double sum = addition (4.2, 3); will call d option: double addition(double x, double y)
