Certified Arborist Practice Exam

The three components of risk assessment in arboriculture are the potential for failure, targets, and consequences. When assessing the risk of tree failure, arborists consider the likelihood of the tree or its parts failing (potential for failure), the potential targets that could be affected if the failure were to occur, and the potential consequences of such a failure. Therefore, option B, "Potential for failure," is the correct answer in this case.

Options A, C, and D are not directly related to the components of risk assessment and are not the correct choices.
