Wanted to confirm whenter the following sentence is true or false:

"Assigning null to a reference causes the object to become eligable for garbage collection "

As I was solving one mock exam and I choose this answer as true but my answer was wrong so just got confused....

also please provide some details on this.

That statement is correct if the only reference to an object is assigned null.
However, there may be many variables referring to an object. Assigning any *one* of them does not make the object eligible for garbage collection. However, if *all* of them are assigned null then the object will be eligible for GC.
