A reference parameter is an alias for its corresponding argument and is declared by following the parameter's type in the function prototype by an ampersand (&). In other words, it allows a function to modify the value of its corresponding argument directly, rather than working with a copy of the argument. Therefore, both (a) and (b) are correct. (c) is incorrect, as reference parameters can be modified.
