D:- Typhoid EXPLANATION; when you uploaded a chaprer named as the prokaryotes tou tokd there that antibiotics are only use when one has any bacterial infections onlyy. And an antibiotic can never be used for any other viral or neither viral nor bacterial infections such as malaria and if one use antibiotics for non bacterial infection then antibiotic resistance will be developed in the body and next time when you are suffering from any bacterial infection that antibiotic won't work. hope you guys got me only if I'm correct
