Choose the figure that is different from the rest based on structural division:

- AA circle divided into 4 equal quadrants with 1 part shaded.
- BA square divided into 4 equal smaller squares with 1 part shaded.
- CAn equilateral triangle divided into 4 smaller identical triangles with 1 part shaded.
- DA rectangle divided into 4 unequal parts with 1 part shaded.
Solution & Step-by-step Explanation
In options A, B, and C, the geometric figures are divided into 4 completely equal and identical parts. However, in option D, the rectangle is divided into 4 unequal parts. Therefore, option D is different from the rest.
