Question

which picture has symmetry?

Explanation:

Step1: Check first picture

The train has uneven elements like the chimney and the side - window placement, so it's not symmetric.

Step2: Check second picture

The food - cover has a central line of symmetry. If we draw a vertical line through the middle, both sides match exactly.

Step3: Check third picture

The bitten - off watermelon is not symmetric as the bite creates an uneven shape.

Answer:

The second picture (the food - cover) has symmetry.
