(python) appreciated!
a static member of some classx (check all that apply):
1)can have associated mutators and/or accessors.
2)can be deleted by a client, making future access of this static/class member by other objects of that class impossible.
3)can, at any given time, store one value for obj_a and a different value for obj_b, two different objects of classx.
4)can be modified from any client (like main program) even if the client has not instantiated an object of classx.

Consider the following code snippet: #ifndef cashregister_h#define cashregister_hconst double max_balance = 6000000.0; class cashregister{public: cashregister(); cashregister(double new_balance); void set_balance(double new_balance); double get_balance() const; private: double balance[12]; }; double get_monthly_balance(cashregister bk, int month); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_balance should be removed since header files should not contain constants.c)the definition of cashregister should be removed since header files should not contain class definitions.d)the body of the get_monthly_balance function should be added to the header file.
