Step 1: Treat this as a visual pattern series. We are shown a sequence of grid figures and must choose the figure that continues the pattern. Step 2: Track one element at a time. In such series, each icon usually moves a fixed number of cells per step while keeping or toggling a marker (such as circled versus dashed). Step 3: Note the movement rule. Comparing consecutive given figures, the icons shift by a consistent step and rotate their highlighted status in a fixed cycle. Step 4: Apply the rule to the last frame. Carrying the same shift one more step from the final shown figure predicts the exact placement of every icon in the missing figure. Step 5: Match the prediction to the options. The predicted arrangement of positions and markers lines up only with the layout shown in Figure 1. Step 6: Conclude. Hence the missing figure is Figure 1. \[ \boxed{\text{Figure 1}} \]
