Depends on how deep you're willing to go to really,
You need one of a few arrangements of flip flop circuits to keep 1-bit state.
Going deeper, you need either NAND, or NOR gates(or a bunch of other ones) and connectors.
Even deeper, you'll require diodes or transistors to build the logic gates.
Beyond that is particle physics.
I am.

I would go straight to the bank and have it reported along with the police.
Choice C. Choice C includes uppercase and lowercase leters, has a number, and two characters.
