Without having counted everything, I would guess it would have to Switzerland. All rectangular flags can only have two lines of symmetry at most. However, here are only two national flags that are squares (we'll be ignoring Nepal because,,, obviously): Switzerland and the Vatican City. And since the Vatican flag has a whole coat of arms on it, it must be Switzerland, which has the vertical line, the horizontal line, and two diagonals; a whopping four lines!
Bangladesh and Japan flags has the most symmetrical flags.
Most parallelograms do not have any lines of symmetry. The only parallelograms that can have lines of symmetry are squares, rectangles, and rhombuses.
A trapezium can have at most 1 line of symmetry.

One. With most butterflies, their left side is the exact opposite of their right side.
no most definitely not
India
the empty flag.
Yes because it has infinite lines of symmetry.
Most parallelograms do not have any lines of symmetry. The only parallelograms that can have lines of symmetry are squares, rectangles, and rhombuses.
It is a circle whose lines of symmetry are infinite
A circle. It has an infinate amount of lines of symmetry.
No it's not possible. The triangle with the most lines of symmetry is Isosceles triangle and that has 3 lines of symmetry. Unless you draw on the back, but that isn't correct.
Yes, most (non-regular) hexagons do not have lines of symmetry.
Most shapes do not have lines of symmetry so why should it come as a surprise that a parallelogram has none?
A trapezium can have at most 1 line of symmetry.
