B,

If you look at FED unprecedented move, you will notice that the rescue is NOT take over like F/F, but FED is ONLY injecting 85B to the troubled AIG. By doing so, the FED would get about 80% stake in the company. This firm is also too big to fail, and the money FED is lending is only for 24 months. This is NOT the takeover but only a big chunk of loan.
