Assume the following definition of a method in Java:

public static void increment(int x) {

x++;

}

Additionally, the following statements are declared in the main method:

int x = 20;

increment(x);

Accordingly, which of the following statements is correct?

Select one:

a. Before the call x = 20, inside the method x = 21, after the call x = 21

b. Before the call x = 20, inside the method x = 20, after the call x = 20

c. Before the call x = 20, inside the method x = 21, after the call x = 20

d. Before the call x = 20, inside the method x = 20, after the call x = 21
