Two customer feedback surveys (Survey A conducted pre-launch, Survey B post-launch) show differing opinions on a new product's ease of use. Survey A indicated 85% found it easy, while Survey B indicated only 60%. A separate internal memo notes a significant software update between the surveys. Which conclusion is most reasonable?
✓ Correct Answer: Option A
A decrease in perceived ease of use (85% to 60%) coupled with a significant software update between surveys strongly suggests the update was a causal factor for the decline in ease of use.
