1. public class Person { 2. private String name； 3. public Person（String name） { this.name = name； } 4. public boolean equals（Person p） { 5. return p.name.equals（this.name）； 6. } 7. } Which is true？（）
- A The equals method does NOT properly override the Object.equals method.
- B Compilation fails because the private attribute p.name cannot be accessed in line 5.
- C To work correctly with hash-based data structures， this class must also implement the hashCode method.
- D When adding Person objects to a java.util.Set collection， the equals method in line 4 will prevent duplicates.
