G is correct. An error at line 10 causes a NullPointerException to be thrown because e2 wasset to null in line 8. If line 10 was moved between lines 7 and 8, then F would be correct,because until the last reference is nulled none of the objects is eligible, and once the lastreference is nulled, all three are eligible.A, B, C, D, E, and F are incorrect based on the above.
