B
Correct Answer
Rebuilding only the subtree that depends on an animation, keeping static parent widgets from rebuilding unnecessarily
Explanation
AnimatedBuilder rebuilds only the widget returned by its builder function when the animation changes. The optional child parameter lets you pass a static sub-widget that is built once and passed into the builder without rebuilding.
