Broad spectrum antibiotics are the ones which attack
The correct option is (C) A wide range of pathogens
A broad-spectrum antibiotic is defined as an antibiotic that works against a variety of disease-causing bacteria, as well as the two main bacterial types: Gram-positive and Gram-negative. When a bacterial infection is suspected but the type of bacteria is uncertain, or when infection with several types of bacteria is suspected, these drugs are employed. This contrasts with a narrow-spectrum antibiotic, which works solely against a certain class of bacteria. Broad-spectrum antibiotics, despite their strength, come with many drawbacks, most notably the disturbance of native, healthy bacteria and the emergence of antibiotic resistance. Ampicillin is a well-known example of a broad-spectrum antibiotic.
Another example of broad-spectrum antibiotics is ciprofloxacin, which is mostly used to treat several infections, including urinary tract infections and respiratory infections. It acts against most Gram-negative bacteria. Besides, many Gram-positive bacteria are also moderately susceptible to this antibiotic.
