Which equality tests are true

A class Owl has data members kind and weight, and overrides equals method. It also overrides hashCode, because any class that overrides equals should override hashCode too:

// import java.util.Objects;
class Owl {

 public Owl( String k, int w ) { 
  kind = k; 
  weight = w; 
 }

 @Override 
 public boolean equals(Object o) {
  return o == this || 
        ( o instanceof Owl && 
        Objects.equals(((Owl)o).kind, kind) && 
        ((Owl)o).weight == weight );  
 }

 // Override hashCode also
 @Override 
 public int hashCode() {
    return Objects.hash(kind, weight);
 }

 // ... more methods

 private String kind;
 private int weight;
}

Class Owl is used as follows:

Owl o1 = new Owl("Barn", 20);
Owl o2 = new Owl("Barn", 20);
Object o3 = o1;

Select all the equality tests on o1, o2, and o3 below that would return true:
