The correct answer is B. A harmless organism imitating the look of a harmful organism
Step-by-step explanation:
In biology, mimicry is a mechanism in which one organism resembles or imitates another. This helps organisms to avoid predation. For example, if a harmless organism such as a Mexican milk snake imitates the look of a harmful organism such as a coral snake, predators will avoid eating the milk snake thinking it is the dangerous coral snake. Thus, the one that is an example of mimicry that enables prey species to avoid predation is a harmless organism imitating the look of a harmful one (option B).
