Final answer:
The need to close distance should be evaluated by asking if the threat can be eliminated, if the suspect's movement can be restricted or isolated, and if resources can be taken away from the suspect. So, the correct answer is option d.
Step-by-step explanation:
The correct answer to the question, 'When evaluating the need to close distance, you should ask which of the following?' is d. All of the above questions should be asked. It is important to consider all three questions because they address different aspects of the situation. By evaluating if the threat can be eliminated, if the suspect's movement can be restricted or isolated, and if resources can be taken away from the suspect, law enforcement can make informed decisions when closing distance.
