Answer: (D)

Verified step by step guidance

1. Understand that Gestalt principles explain how we naturally organize visual elements into groups or unified wholes.
2. Identify the principle that relates to perceiving elements arranged in a line or smooth path as connected rather than separate.
3. Recall that the principle of continuity states that we tend to perceive continuous lines or patterns rather than disconnected segments.
4. Apply this principle to the series of dots arranged in a straight line, which leads us to see them as a single continuous unit.
5. Contrast this with other principles like similarity, proximity, and closure, which explain grouping based on shared features, closeness, or completing incomplete shapes, respectively.
