If alpha and beta Are different complex number with |alpha|=1, then what is |(alpha- beta)/(1-alpha beta)| equal to ?

If alpha,beta are different complex numbers with | beta|=1 then |(alpha-beta)/(1-alphabar(beta))|=(i)0(ii)(1)/(2)(iii)1(iv)2

If alpha and beta are complex numbers then the maximum value of (alpha barbeta+baralphabeta)/(|alpha beta|)=

If alpha and beta are the complex cube roots of unity, then what is the vlaue of (1+alpha)(1+beta)(1+alpha^(2))(1+beta^(2)) ?
