The most likely source of error in this investigation would be:
She dropped the balls from different heights.
This is because the height from which an object is dropped affects the time it takes to hit the ground, and for a valid investigation into gravity and falling objects, it's important that all balls are dropped from the same height. The other options provided do not significantly impact the investigation as they are less relevant to timing and the effect of gravity.
