The correct option is C Actinomycin
In 1940, Woodruff and Waksman isolated and purified actinomycin from Actinomyces griseus (later named Streptomyces griseus). Actinomycin is an antibiotic which inhibits the growth of gram-negative bacteria and thus, used to treat typhoid, dysentery, cholera, and undulant fever.
