Right choice is (b) Anionic drug
To elaborate: Anionic or acidic drugs bind to HSA easily, for example, penicillin and sulphonamides. Cationic or basic drugs bind easily to alpha 1 acid glycoprotein, for example, imipramine and alprenolol. Neutral and unionized drugs bind to lipoproteins. Lipophilic drugs localize more into adipose tissue.
