US State flags with reflectional symmetry are:AlabamaArizonaColoradoNew MexicoThe flag of Maryland appears to have rotational symmetry at first glance, but in fact the colours are rotated in each canton (corner).Similarly, Ohio's flag appears to have reflectional symmetry, but the stars in the flag are rotated in the bottom half of the triangle on the left-hand side.

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!
2 lines of symmetry
They all do.
A nephroid has 2 lines of symmetry.
