Option A and C are valid function prototypes with variable names missing but the use of variable names is good programming practice as it helps in understanding the code. 
Option B is invalid as it is missing the return type.
Option D is the best choice as it has all the necessary components: return type, function name, and parameter list with data types and variable names.
