Which medication is considered the most effective for treating asymptomatic amoebic cyst carriers?

Explanation

Among the listed drugs, Diloxanide furoate is the preferred treatment for asymptomatic individuals harboring amoebic cysts, as it effectively eradicates the cyst form in the intestines. Metronidazole and others are primarily active against the trophozoite stage but are less effective against cysts.
