spatial visualization

c
d
e

Explanation:

Step1: Analyze the sequence rules

The sequence shows: 1) A full square, 2) A right half of the square, 3) The right half split into a top rectangle and bottom triangle, 4) The bottom triangle gets a single circle. The circles mark the "newly added/modified" split points or features: each step adds a circle at the location of the split/change.

Step2: Map circle positions

• Step1: No splits, no circles.
• Step2: Split at the vertical middle left, so a circle would be at that left middle (but not shown yet, building up).
• Step3: Split the right half at the bottom corner, adding a circle at that bottom right split.
• Step4: Add a circle inside the triangle, which is the bottom right split area.

The pattern is that each split creates a circle at the split vertex, and we end up with two circles at the bottom split vertices and two at the left/right middle split vertices, matching option C.

Answer:

C. <The square with two circles at the bottom corners and two circles in the middle top area>
