Step 1: Understanding mirror reflections.
When a figure is reflected in a mirror, its orientation is reversed left-to-right. Each additional reflection flips it again. Therefore, the direction of the arrow changes with every reflection depending on which side the mirror is placed.
Step 2: Explanation.
In the given sequence, the pentagon undergoes four reflections across alternating mirror lines. Because the angles and sides of the pentagon are not symmetric, each reflection alters the arrow’s position relative to the vertices. Tracking the arrow through all four flips, its final orientation matches the one shown in **Option A**, not Option B.
Step 3: Conclusion.
Thus, after four reflections, the final arrow position corresponds to **Option A**.
