To call a C/C++ function with a function return value, the correct option is A) (a) CALL . . . RETURNING.
Explanation:
In C/C++, when you want to call a function and use its return value, you can use the syntax:
return_type variable = function_name(arguments);
For example, if you have a function named add that takes two integers as arguments and returns their sum, you can call it and store the result in a variable like this:
int result = add(3, 5);
In this case, the function add is called with the arguments 3 and 5, and the return value is assigned to the variable result.
Therefore, the correct option is A) (a) CALL . . . RETURNING.
