Assume a function F1 is defined with the heading: void F1(int a, double &b, double t[] ) ; Assume the following statements: int a1; double b1, double t1[50]; have values and are given in main().The statement that correctly calls function F1 is

1. F1(a1, b1, t1);

2. F1(a1, b1+ a1, t1);

3. cout << F1(a1, b1, t1);

4. F1(int a1, double &b1, double t1[]);
