A Correct answer
Explanation

In COBOL, when calling a subprogram that returns a value, the correct syntax is 'CALL identifier USING ... RETURNING identifier'. The RETURNING clause captures the function's return value. Options B, C, and D use incorrect keywords (RECURRING, RECURSIVE, REFERRING) that are not valid in this context.

AI explanation

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.
