  1. Correct Answer – B
    `a=0 rArr sin (2 theta-b)=0`
    `rArr 2 theta-b=n pi, n in Z`
    `rArr theta=(n pi+b)/2, n in Z, S_(2)=(n pi +b)/2, n in Z`
    `S_(2)` is subset of `(0, pi)`
    `:. 0 lt (n pi +b)/2 lt pi, n in Z`
    `:. 0 lt n pi +b lt 2pi rArr -n pi lt b lt -n pi +2pi`
    `rArr b in (-n pi, 2pi-npi), n in Z`
