• A. Infestation
• B. Infest
• C. Habitat
• D. Organism

Answer: (A)

Infestation describes a state of pest presence where numbers are high enough to cause damage or nuisance. It’s the term used for a pest problem—the population has overrun the area and is harmful or unpleasant. The action form “infest” is a verb, not the description of the condition. Habitat refers to the living environment of an organism, and organism is the living creature itself. So the term that best fits a pest population that is problematic is infestation, the condition of having pests in troublesome numbers.
