Option D is the best option as it matches the requirements of passing three integer variables and returning an integer value. Option A is incorrect as it does not specify the data type of the variables in the procedure header. Option B is also correct but redundant as the data types are repeated in the header. Option C is incorrect as it includes an additional ByRef parameter that is not needed for the given requirements.
