Which statement is false?

Question

a ¡ô {a, b, c}
¨ª ¡ø {a, b, c}
¨ª ¡ö {a, b, c}
¨ª ¡ô {a, b, c}

Answer 1

I cannot read the symboles in the different choices.

If you find one which reads:
a ∉ {a,b,c}
it would be false.

Alternatively, if you would repost using encoding: Western ISO-8859-1, it will be understandable to me.
