B) Narrow spectrum
C) Bactericidal
D) Bacteriostatic
B
Feedback:
Some anti-infectives are so selective in their action that they are effective against only a few, or possibly only one, microorganism with a very specific metabolic pathway or enzyme. These drugs are said to have a narrow spectrum of activity. They are not called broad spectrum, which applies to a drug with little selectivity; bactericidal, which is a substance that causes death of bacteria; or bacteriostatic, which prevents replication of a bacterium.
