1 Answer

Answer :

(3) Penicilin Explanation: Penicillin is a group of antibiotics derived from Penicillium fungi. They include penicillin G, procaine penicillin, benzathine penicillin, and penicillin V. Penicillin antibiotics are historically significant because they are the first drugs that were effective against many previously serious diseases, such assyphilis, and infections caused by staphylococci and streptococci.
