C) Selective.
D) Multi-target.

Answer 1

Broad-spectrum antibiotics affect both gram-negative and gram-positive bacteria.

Step-by-step explanation:

Antibiotics that affect both gram-negative and gram-positive bacteria are called broad-spectrum antibiotics. These antibiotics are effective against a wide range of taxonomic groups and target diverse subsets of bacterial pathogens. The use of broad-spectrum antibiotics is preferred in certain cases, such as when waiting for laboratory identification of the infecting pathogen or when treating polymicrobic infections.
