Solution
The correct option is D Self perpetuating
The biological method is the technique in which there is the use of living microorganisms or its product for the control of pests. This method uses the microbes which act as predators or enemies of the target pest species. The biological control method is often relatively inexpensive because the method uses the microorganisms which can be easily cultured. These are beneficial microorganisms which are used, so they do not contribute the pollution. If biocontrol agents are introduced in any area, survive for multiple years and become self-perpetuating. They will spread over a large area over time and continue to exist for a very longer period. Thus, the correct answer is option C.
