How to determine that an object overlaps several other objects?

Hello, could you please help me solve one question? I have several instances of object A, some of these instances overlap instances of object B. I need to determine which instances of object A overlap two instances of object B. And then make them invisible. Could you please tell me how this can be done?

My approach would be to add an instance var to 'A'. Then you say for each 'A', 'A' is overlapping 'B', set 'A'.variable to 'B'.pickedcount.
