Consider the following DataProcessor class, which contains several overloaded process methods.

public class DataProcessor {
    public void process(Object data) { /* implementation A */ }
    public void process(String text) { /* implementation B */ }
    public void process(Integer number) { /* implementation C */ }
    public void process(int value) { /* implementation D */ }
}

Now, consider the following code segment that utilizes the DataProcessor class:

DataProcessor dp = new DataProcessor();
String str = "hello";
Integer intObj = 42;
int intPrim = 42;
Object obj = "world";

dp.process(str);     // Call 1
dp.process(intObj);  // Call 2  
dp.process(intPrim); // Call 3
dp.process(obj);     // Call 4

Which statement correctly identifies the implementation invoked by each method call?
