Answer:
The answer is "Option d".
Explanation:
In this question the choice d, that is "a copy of the variable" is correct because the method takes a reference value or a copy of the variable in its parameter, the example of this question can be defined as follows:
void me2(double x)//defining a method me2 with a double parameter
{
//method body
 }
double x = 35.655;//defining a double variable x
me2(x);//calling a method with passing the copy of th e variable
