Resp arrest because alcohol and benzo are CNS depressants. Delirium tremens occurs after a few days due to alcohol withdrawal.

Actually i just read the an overdose of TCA leads to arrythmia and cardiac arrest, I would say in this case cardiac arrest. (benzos and alcohol would lead to resp depression- not sure if it leads to respiratory arrest)

TCA's SE are 3Cs: Coma, Convulsions, Cardiotoxicity. I think i would have chosen #2 because coma + alchool- and benzo-induced resp depression sounds to me as a high risk for resp arrest. But anyway am not sure...
