Which of the following has only one line of symmetry?

Answer: B. Indian flag

When we fold an Indian flag in a vertical line of symmetry we can see orange on top of orange, white on top of white, green on top of green and Ashok chakra also perfectly overlapping. But when we fold it in a horizontal line of symmetry orange will come on top of green. So it only has one line of symmetry and thus is the correct answer.
