All three are perfectly fine, 2 is perhaps more typical of everyday speech, 1 and 3 are preferred for writing, and to my eye 3 is smoother and more stylish than 1. Also, you used 'among' here rather than 'between'; the distinction can be tricky (see https://blog.oxforddictionaries.com/2015/06/29/grammar-myths-among-or-between/) if in doubt, you are safer using 'of' instead.

More native would be 1 or 3 but all three would be understood.

Of course the second one is correct but the first and third one looks more native and appropriate.

Hi , it's the second one :)
