Which regular expression, inserted at line 12, correctly splits test into "Test A", "Test B", and "Test C"?

Given:

11. String test = “Test A. Test B. Test C.”;
12. // insert code here
13. String[] result = test.split(regex);

Which regular expression, inserted at line 12, correctly splits test into “Test A”, “Test B”, and “Test C”?

A.
String regex = “”;
Test
Test
Compilation fails because of an error in line 3.

B.

QUESTION 2
Given:
1. interface A { public void aMethod(); }
2. interface B { public void bMethod(); }
3. interface C extends A,B { public void cMethod(); }
4. class D implements B {
5. public void bMethod(){}
6. }
7. class E extends D implements C {
8. public void aMethod(){}
9. public void bMethod(){}
10. public void cMethod(){}
11. }
What is the result?
Compilation fails because of an error in line 9.

D.
String regex = “\\s”;
If you define D e = new E(), then e.bMethod() invokes the version of bMethod() defined in Line 5.

E.
String regex = “\\.\\s*”;
If you define D e = (D)(new E()), then e.bMethod() invokes the version of bMethod() defined in Line 5.

F.
String regex = “\\w[ \.] +”;
If you define D e = (D)(new E()), then e.bMethod() invokes the version of bMethod() defined in Line 9.
