Analyze the following code:
public class Test1 {
public Object max(Object o1, Object o2) {
if ((Comparable)o1.compareTo(o2) >= 0) {
return o1;
}
else {
return o2;
}
}
}
Group of answer choices
A. The program has a compile error because Test1 does not have a main method.
B. The program has a compile error because o1 is an Object instance and it does not have the compareTo method.
C. The program has a compile error because you cannot cast an Object instance o1 into Comparable.
D. The program would compile if ((Comparable)o1.compareTo(o2) >= 0) is replaced by (((Comparable)o1).compareTo(o2) >= 0).
