Which statement best describes the rupture risk over five years for a 7 cm AAA?

Explanation:
Rupture risk for an abdominal aortic aneurysm climbs as the aneurysm grows because wall tension increases with size (Laplace’s law). When the dilation reaches about 7 cm, the cumulative chance of rupture within the next five years becomes very high—roughly three-quarters of patients. In practical terms, this means that if the aneurysm is left unrepaired, the probability of rupture over five years is around 75%. This high risk with a 7 cm aneurysm is why such sizes are treated seriously, often with elective repair, rather than watchful waiting. The options suggesting much lower or near-total risk don’t align with how the rupture risk behaves at this diameter.
