Acetazolamide mannitol

What is the process that acetazolamide utilizes to induce diuresis?

1: Inhibiting sodium channels in the distal convoluted tubule
2: Blocking sodium-potassium-chloride co-transporter in the ascending loop of Henle
3: Inhibiting carbonic anhydrase enzyme to reduce bicarbonate absorption
4: Blocking aldosterone receptors to prevent sodium absorption
