Correct answer is B. Answer D, "Immediate jump into detailed risk assessment" is a pitfall of "High-Level risk assessment"

We must select methodologies for identifying and prioritizing these risks and then execute those methodologies. We must identify them upfront and provide the structure for the rest of the risk assessment. We want to involve the stakeholders identified during the initiate step. The common pitfall here is to immediately jump into a detailed risk assessment. It's easy to do, especially with technical stakeholders. We have this shiny object syndrome that we tend to do, "Ooh, look at that. I'm going to go chase that for now. Ooh, look, I want to chase that for now." Avoid that shiny object syndrome, especially when you're doing the risk assessments. You get to see some cool things but you've got to stay focused and stay on track. IC32M page 190
