Statement C is false because risks differ substantially in both probability and impact. Risk assessment exists precisely to distinguish more significant risks from less significant ones.

SCRUMstudy defines risk as an uncertain event or set of events capable of affecting project objectives positively or negatively. Positive risks are called opportunities, while negative risks are threats.

Risk management is iterative and begins during project initiation, continuing throughout the project lifecycle. Risks are assessed primarily on their probability of occurrence and potential impact. Risks with high probability and high impact should generally receive greater attention than low-probability, low-impact risks.

This prioritization enables limited resources to be allocated rationally. Techniques such as Probability Impact Grids, Probability Trees, Expected Monetary Value, and Pareto Analysis help teams assess and compare exposures.

Therefore, the claim that all risks possess equal probability and impact directly contradicts the central mechanism of SBOK risk assessment and prioritization.
