The following picture shows a bacterial lawn in an agar plate with few clear zones. The zones are formed due to a chemical present in the disk at the centre of each zone. This chemical brings about a breakdown of bacterial cells and hence the clear zones. What is this chemical called and what are the primary sources of it?
Bacterial culture plate with clear zones

The correct option is D Antibiotics, bacteria and fungi
Alexander Fleming, in 1928, was working with bacterial cells on agar plates. He suddenly noticed clear zones in the plates unattended for a few days and then he also observed that a mould was growing in these plates. The mould was identified as Penicillium. Later, the chemical substance isolated from Penicillium was called as antibiotic Penicillin.
Antibiotics are the substances/chemicals which bring upon the breakdown/lysis of the bacterial cells and hence are used to treat diseases in humans. Bacteria and certain fungi are the primary sources of antibiotics.
