Correct answer: A — Physical activity supports vascular health, function and cognitive resilience

The best answer is “Physical activity supports vascular health, function and cognitive resilience”. Physical activity maintains vascular health, supports functional capacity, and preserves cognitive resilience The alternatives “Exercise reverses cognitive decline immediately, with multidisciplinary review”, “Strength training offers no benefit for functional independence in older age”, “Aerobic exercise becomes unsafe beyond age 75”, “Balance and coordination training is valuable for athletic individuals” are credible in related presentations but do not match the defining finding, treatment threshold, legal test or care pathway in this stem.
