Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why has antibiotic resistance evolved in bacteria?
A
Bacteria reproduce quickly
B
Bacteria with a resistant to the antibiotic passed that trait to offspring
C
Bacteria that are resistant reproduce faster than non resistant strains
D
Bacteria exposed to antibiotics develop a resistance to them
Explanation: 

Detailed explanation-1: -Antimicrobial resistance is accelerated when the presence of antibiotics and antifungals pressure bacteria and fungi to adapt. Antibiotics and antifungals kill some germs that cause infections, but they also kill helpful germs that protect our body from infection. The antimicrobial-resistant germs survive and multiply.

Detailed explanation-2: -The development of generations of antibiotic-resistant microbes and their distribution in microbial populations throughout the biosphere are the results of many years of unremitting selection pressure from human applications of antibiotics, via underuse, overuse, and misuse.

Detailed explanation-3: -Misuse and overuse of antimicrobials are the main drivers in the development of drug-resistant pathogens. Lack of clean water and sanitation and inadequate infection prevention and control promotes the spread of microbes, some of which can be resistant to antimicrobial treatment.
