Solution

The correct option is D Penicillin
Penicillin is a secondary metabolite of certain species of Penicillium and is produced when the growth of the fungus is inhibited by stress. It is not produced during active growth. Production is also limited by feedback in the synthesis pathway of penicillin. It was discovered by Alexander Fleming.
So, the correct option is 'Penicillin.
