The Correct Option is D
Solution and Explanation
Concept:
Step 1: Study the structure of the original figure.
A circle at the centre is cut into 4 parts by two crossing diagonal lines, and an outward-pointing petal sits on each of the four sides of the square, each petal carrying a small mark near its tip.
Step 2: Check the diagonal-cross part of the figure.
The diagonal cross inside the circle is symmetric about both the vertical and horizontal centre lines, so it looks the same before and after the mirror flip and cannot be used to tell the options apart.
Step 3: Check the four petals, which are the deciding feature.
Reflecting the figure along the vertical line MM' must keep the top and bottom petals exactly as they are, but must swap the left and right petals with each other, reversing the side on which each petal's tip-mark sits.
Step 4: Compare with the options.
Most of the options keep the left and right petal marks positioned exactly as in the original figure, which is incorrect for a left-right mirror.
Only one option correctly reverses the tip-mark's side on the left and right petals while leaving the top and bottom petals unchanged.
Final Answer: Option 4
- A mirror image formed along a vertical line MM' flips the figure left-to-right: whatever sits on the left of the centre appears on the right in the reflection, and vice versa, while anything directly above or below the centre (top and bottom) stays exactly where it was.
- Any part that is not symmetric left-to-right (such as a mark placed only on one side of an arrow-shaped petal) must also have its position swapped in the reflection.
