studentObject.ln = lastname;
studentObject.addr = address;
studentObject.db = DOB;
}

B.The values in the right side of the equations are not the same as the argument list.
C.There is not enough variation in the code to create new copies of this object.
D.The variables are too generic; Ling needs to assign each student a personal ID, or a number that defines each as an individual.
