B
Correct Answer
ListView builds all children at once; ListView.builder lazily builds only visible items on demand
Explanation
ListView takes a children list and builds all widgets upfront — suitable for small, fixed lists. ListView.builder lazily builds only the visible items using an itemBuilder function. This makes it memory-efficient for long or infinite lists.
