Unique (text) value for Randbetween

Here is my request:

I have one question A1 with four possible answers. (A2,A3,A4,A5)

=INDEX($A$2:$A$5; RANDBETWEEN(1;4))

But this one will give me double results, for ex. A2,A3,A3,A2. I try with RAND function but no success.

=INDEX($A$2:$A$5;RAND()*4+1; RANDBETWEEN(1;4))

Anybody have any idea how to solve this problem?

Thx
