Which of the answer figures is the exact mirror image of the given problem figure when the mirror is held at the right side?

Problem figure:

To determine the correct mirror image of the problem figure when the mirror is placed on the right side, we can analyze the transformation of each of the four quadrant sub-figures.

When a mirror is held at the right side of a figure, the left and right positions of all elements inside the figure are reversed (reflected horizontally), while the top and bottom positions remain unchanged.

Let us analyze each sub-figure of the problem figure (image_0.webp):

1. Top-Left Sub-figure:
- In the problem figure, this contains a downward-pointing black triangle, with a hollow white circle on its left and a solid black pentagon on its right.
- In the mirror image, this sub-figure reflects to the Top-Right position. The hollow white circle (on the left) moves to the right, and the solid black pentagon (on the right) moves to the left.
- Thus, the Top-Right quadrant of the mirror image must have a downward-pointing black triangle, with a solid black pentagon on its left and a hollow white circle on its right.

2. Top-Right Sub-figure:
- In the problem figure, this contains a downward-pointing white triangle, with a solid black pentagon on its left and a solid black circle on its right.
- In the mirror image, this sub-figure reflects to the Top-Left position. The solid black circle (on the right) moves to the left, and the solid black pentagon (on the left) moves to the right.
- Thus, the Top-Left quadrant of the mirror image must have a downward-pointing white triangle, with a solid black circle on its left and a solid black pentagon on its right.

3. Bottom-Left Sub-figure:
- In the problem figure, this contains an upward-pointing white triangle, with a solid black circle on its left and a hollow white pentagon on its right.
- In the mirror image, this sub-figure reflects to the Bottom-Right position. The solid black circle (on the left) moves to the right, and the hollow white pentagon (on the right) moves to the left.
- Thus, the Bottom-Right quadrant of the mirror image must have an upward-pointing white triangle, with a hollow white pentagon on its left and a solid black circle on its right.

4. Bottom-Right Sub-figure:
- In the problem figure, this contains an upward-pointing black triangle, with a solid black pentagon on its left and a hollow white circle on its right.
- In the mirror image, this sub-figure reflects to the Bottom-Left position. The solid black pentagon (on the left) moves to the right, and the hollow white circle (on the right) moves to the left.
- Thus, the Bottom-Left quadrant of the mirror image must have an upward-pointing black triangle, with a hollow white circle on its left and a solid black pentagon on its right.

Comparing these requirements with the given answer figures, we find that the second figure (Option 2) perfectly matches all the reflected characteristics described above.
