Review this image of the H. pylori bacteria:

Image of the H. pylori bacteria with the words 'normal (produces enzyme)' under it, with an arrow pointing to the dead bacteria that has the words 'antibiotic applied' over it and the word 'death' under it; image of the H. pylori bacteria with the words 'mutant (produces NO enzyme)' under it, with an arrow pointing to the alive bacteria with the word 'survives' under it.

What inference can be made based on this image?

A localized infection must be treated with antivirals.
Some pathogens may become antibiotic-resistant.
Antibiotics effectively stop viral infections.
Antibodies adapt to enzymatic viruses.
