Explanation:

Step1: Analyze the cut-out shape

The removed corner is a small right triangle, which matches the smaller triangle in the third figure.

Step2: Locate the hole position

The hole is on the larger triangle that remains attached to the main square. This hole is positioned near the top-right (relative to the original square) and closer to the hypotenuse of the larger triangle.

Step3: Match to the option

Compare the hole positions: Option D has the three dots matching the positions of the hole and the two corners of the cut area, aligning with the spatial arrangement from the original square and the removed piece.

Answer:

D. <The square with dots at bottom-left, middle-left, and top-right corners>
