There Exists a Data Type Date with Member Function Increment

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is being overloaded to postincrement an object of type Date. Select the correct implementation:

A) Date Date::operator++(int) {
Date temp{*this};
Increment() ;
Return *temp;
}
B) Date Date::operator++(int) {
Increment() ;
Date temp{*this};
Return temp;
}
C) Date Date::operator++(int) {
Date temp{*this};
Return this;
Temp.Increment() ;
}
D) Date Date::operator++(int) {
Date temp{*this};
Increment() ;
Return temp;
}
