Question
Which statement is true?a) When an argument is passed call by reference, a copy of the argument's value is made and passed to the called function.
b) With call by reference, changes to the passed value do not affect the original variable's value in the calling functions.
c) Call by value should be used whenever the called function does not need to modify the value of the caller's original value.
d) Call by value should only be used with trusted called functions that need to modify the original variable.

Q3[C++11]: Which of the following statements about inheriting base class constructors is false?
