When is the Demo object eligible for garbage collection?

1.	When is the Demo object eligible for garbage collection?
Answer» Option D is correct. By a process of elimination. Option A is wrong. The variable d is a member of the Test class and is never directly set to null. Option B is wrong. A copy of the variable d is set to null and not the actual variable d. Option C is wrong. The variable d exists outside the start() method (it is a class member). So, when the start() method finishes the variable d still holds a reference.
