Streptomycin is an aminoglycoside antibiotic used to treat bacterial infections like tuberculosis. Griseofulvin is an antifungal antibiotic used to treat fungal infections of the skin, hair, and nails. Quinine is an antimalarial drug, not an antibiotic - it treats protozoan infections (malaria), not bacterial ones. Therefore, only options 1 and 2 are antibiotics.
