Analyze the following code.

```
public class Test {
int x;

public Test(String t) {
System.out.println("Test");
}

public static void main(String[] args) {
Test test = null;
System.out.println(test.x);
}
}```
a. The program has a compile error because test is not initialized.
b. The program has a compile error because x has not been initialized.
c. The program has a compile error because you cannot create an object from the class that defines the object.
d. The program has a compile error because Test does not have a default constructor.
e. The program has a runtime NullPointerException because test is null while executing test.x.

e
