public class CreditCard {  private String cardlD；  private Integer limit；  public String ownerName；  public void setCardlnformation（String cardlD，  String ownerName， 28. Integer limit） {  this.cardlD = cardlD；  this.ownerName = ownerName；  this.limit = limit；  }  } Which is true？（） 

• A、 The class is fully encapsulated.
• B、 The code demonstrates polymorphism.
• C、 The ownerName variable breaks encapsulation.
• D、 The cardlD and limit variables break polymorphism.
• E、 The setCardlnformation method breaks encapsulation.
