The correct statement is:
Over the short run, the elasticity of quantity supplied by firms tends to be more like the graph on the right.
In the short run, firms typically have less flexibility to adjust their production levels, resulting in a more inelastic supply curve, which is represented by the gentle slope. In contrast, in the long run, firms have more time to adjust their production capabilities and resources, leading to a more elastic supply curve, which is represented by the steeper slope in the graph on the left.
