- Antibiotic resistance occurs when bacteria evolve to evade antibiotics. Overuse and misuse of antibiotics are the biggest drivers of resistance. That means that the more we use antibiotics, the worse the problem of antibiotic resistance becomes.
- Antibiotics work by binding to a specific target protein on a bacteria, then entering to kill it from the inside. Penicillin, for example, weakens the bacterial cell wall, causing the cell to disintegrate.
- The most common ways bacteria evade antibiotics come from mutations that allow them to stop drugs from binding to bacteria. It’s like the bacteria changed the locks so the antibiotic key no longer opens the cell door.
- Bacteria can also achieve resistance by producing proteins that inactivate or modify the antibiotic, so it no longer binds to the bacteria. Or the target protein is mutated so the antibiotic can no longer bind to it

Explanation:
The correct answer is option 'D' - all the statements 1, 2, and 3 are correct. Let's analyze each statement individually:
Statement 1: Antibiotics work by binding to a specific target protein on a bacteria, then entering to kill it from the inside.
This statement is correct. Antibiotics are chemicals that target specific structures or proteins in bacteria, disrupting their normal function and ultimately killing them. By binding to a specific target protein, antibiotics can inhibit essential cellular processes in bacteria, such as cell wall synthesis or protein synthesis, leading to their death.
Statement 2: Antibiotic resistance occurs when bacteria evolve to evade antibiotics.
This statement is also correct. Antibiotic resistance is the ability of bacteria to withstand the effects of antibiotics, rendering them ineffective. Bacteria can develop resistance through various mechanisms, such as acquiring resistance genes through horizontal gene transfer, mutations in target proteins, or the development of efflux pumps that can pump out antibiotics from the bacterial cell.
Statement 3: Overuse and misuse of antibiotics are the biggest drivers of antibiotic resistance.
This statement is true as well. Overuse and misuse of antibiotics contribute significantly to the development and spread of antibiotic resistance. When antibiotics are used excessively or inappropriately, bacteria are exposed to these drugs for longer periods, increasing the chances of resistance development. Additionally, when antibiotics are not used according to prescribed guidelines, such as not completing the full course of treatment, bacteria that survive the treatment can develop resistance.
In summary:
Antibiotics work by binding to a specific target protein on bacteria, then entering to kill it from the inside. Antibiotic resistance occurs when bacteria evolve to evade antibiotics. Overuse and misuse of antibiotics are the biggest drivers of antibiotic resistance. Therefore, all the statements are correct, making option 'D' the correct answer.
