Final answer:
All of the behavioral objectives are written correctly except option A.
Step-by-step explanation:
In the given options, all of the behavioral objectives are written correctly except option A.
Option A states, 'Upon request, the client will select two personal activity choices from a list of options.' This objective lacks specificity as it does not mention any criteria or measure for selecting the activity choices, making it difficult to assess the client's progress and achievement.
On the other hand, options B, C, and D are all written correctly as they clearly state the desired behavior, provide a specific request, and include measurable criteria.
