Hint 3 of 3
Spin each choice in your mind and find the one whose marks line up exactly like the real button.
Show solution
Approach: match the fixed arrangement of marks (allowing rotation)
- The real button has a heart, several small dots, and a curved mark in a fixed pattern.
- A correct copy can be rotated but must keep the same relative positions and the same number of marks.
- Only button E matches the real button after turning, so the answer is E.
