An important set of risk factors that contribute to the experience of PTSD is

A) genetic disposition to trauma.
B) the context in which the trauma occurred.
C) whether electroshock therapy had been administered immediately after the traumatic event.
D) whether the person scored high on the trauma index.

The context in which the trauma occurred can have a significant impact on the development of PTSD. Factors such as the severity and duration of the trauma, the individual's level of perceived control, and the presence of social support can all contribute to the likelihood of developing PTSD. While genetic factors may play a role in vulnerability to trauma, it is not a definitive predictor of PTSD. Electroshock therapy is not typically used as a treatment for PTSD immediately following a traumatic event. Scoring high on a trauma index may suggest a greater likelihood of experiencing PTSD, but it is not a causal factor.
