For questions 19 - 21, assume that student, employee and retired are all subclasses of person, and all four classes have different implementations of the method getmoney. consider the following code where are the required parameters for the constructors:

person p = new ;
int m1 = p. getmoney( ); // assignment 1
p = new ;
int m2 = p. getmoney( ); // assignment 2
if (m2 < 1) p = new ;
else if (m1 > 5) p = new ;
int m3 = p. getmoney( ); // assignment 3

the reference to getmoney( ) in assignment 1 is to the class

person
student
employee
retired
this cannot be determined by examining the code
