Hint:- Antibiotics are a category of antibiotics that are used to cure certain germ-induced infections. They do not work against virus-caused illnesses such as the common cold or flu.
Complete answer:
A category of drugs that are used to cure diseases are antibiotics. Often, antibiotics are referred to as antibacterials or antimicrobials. Antibiotics should be administered by mouth or by injection as liquids, pills, or capsules. Typically, when they have a critical illness, patients who need to have an antibiotic by injection are hospitalised. Antibiotics are also available to be added to the skin in the form of creams, ointments, or lotions to cure such skin infections. Antibiotics can either inhibit the replication of bacteria or kill them. The immune system can usually kill them before bacteria can spread and cause symptoms. White blood cells (WBC) attack infectious bacteria and the immune system will typically cope and fend off the infection, particularly if signs do exist. However, often the amount of dangerous bacteria is excessive, and it is not possible for the immune system to combat them all. In this case, antibiotics are beneficial. Penicillin was the first antibiotic. In order to combat a number of diseases, penicillin-based antibiotics, such as ampicillin , amoxicillin and penicillin G, are still available and have been around for a long time. So from these discussions we can conclude that antibiotics are commonly used to treat bacterial infections.
Thus, the right option is D.
Note:- The bacteria could become immune if individuals overuse antibiotics or use them inappropriately. This means that, as the bacterium has been able to strengthen its defences, the antibiotic becomes less effective against that form of bacterium. Such antibiotics target bacteria that are aerobic, whereas others function against bacteria that are anaerobic. Oxygen is required by aerobic bacteria and anaerobic bacteria do not. An allergic reaction to antibiotics, especially penicillins, can develop in some individuals. A rash, swelling of the tongue and face, and trouble breathing may be side effects. When using antibiotics, people with impaired liver or kidney function should be vigilant. The kinds of antibiotics they may use or the dosage they get can be affected by this. Antibiotic reactions can be severe and even lethal. They are referred to as anaphylactic responses.
