Is this a homework question? What do you think the answer is?

None. There aren't objects in your code (I see only class definitions).

Seeing as you never instantiate A or B, none.

The exact same code was asked about yesterday, albeit the last time the OP at least included the code part where the instances were created.
This reeks strongly of homework.

Solution 2

How many objects do you instantiate?
That will help you identify your answer.

The constructor for A defines the object B.
However, constructor A itself is never called.

This you have no objects.

You have never initiated an object in the meory with the

C#

new

key word. Therefore is no object there which could be collecteed by the garbage collector.

Solution 1

Where is the object in your code? So none
