• B. World war I
• C. Both A and B
• D. III war of Panipat

Answer 1

Answer: (A)

World war II

Penicillin is a secondary metabolite of certain species of Penicillium and is produced when the growth of the fungus is inhibited by stress. It was used during World War II. It is not produced during active growth. Production is also limited by feedback in the synthesis pathway of penicillin.

So, the correct option is 'World war II'.
