B Correct answer
Explanation

Penicillin is a classic antibiotic that works against bacteria by disrupting their cell wall synthesis, leading to bacterial death. Quinine and Chloroquine are antimalarial drugs (effective against protozoa, not bacteria), while Anti-Tetanus Serum is an antitoxin providing passive immunity rather than an antibiotic.
