Which of the following is a primary use for antibiotics?

The primary use of antibiotics is to inhibit bacterial infections. Antibiotics are specifically designed to target and combat bacterial pathogens, making them effective in treating diseases caused by bacteria, such as strep throat, urinary tract infections, and certain types of pneumonia. They work by either killing the bacteria or inhibiting their growth and reproduction, helping the immune system to eliminate the infection.

In contrast, managing diabetes requires different classes of medications, such as insulin or oral hypoglycemics, which help regulate blood sugar levels. Treating viral infections typically involves antiviral medications, since antibiotics do not affect viruses. Alleviating chronic pain often involves pain relievers or anti-inflammatory medications rather than antibiotics. Therefore, the distinct purpose of antibiotics in targeting bacterial infections is what makes this the correct answer.
