The correct answer is option B. The overuse of antibiotics.

Now-a-days use of antibiotics is very common. The antibiotic is used to kill the disease causing pathogen, but the overuse and the senseless use of the antibiotics cause the pathogen to develop antibiotic resistance. once, the antibiotic resistance is developed, the infection cannot be cured by that antibiotic, which is the main cause of increase in the diseases in society.

it takes hundreds of years to become stable.
