Which of the following events is likely to be the most stressful?

A) predictable events with individual control
B) predictable events with little individual control
C) unpredictable events with individual control
D) unpredictable events with little individual control

D.

Explanation:

A is incorrect because that would likely be the least stressful event with the most control. B is incorrect because it is predictable and you can brace yourself for either a good or bad event. C is incorrect because it is unpredictable, which is stressful, but can be controlled, which makes it less stressful. This leaves us with D because it is unpredictable and cannot be controlled, which leaves the most to chance and does not give you an idea of what the outcome might be.
