If `Delta_(1)` and `Delta_(2)` are respectively areas of incircle and circumcircle of triangle formed by `(0,0), (2,0)` and `(1,sqrt(3))`, then `(Delta_(2))/(Delta_(1))=?`

Delta_(1) and Delta_(2) are respectively areas of in circle and circumcircle of triangle formed by (0,0), (2,0) and (1,sqrt(3)) then which of following is NOT correct (A) Delta_(1)+Delta_(2)=(5 pi)/(3) (B) |Delta_(1)-Delta_(2)|=pi (C) 3Delta_(1)+6Delta_(2)=9 pi (D) [2Delta_(1)+3Delta_(2)]=12 , where [.] is G.I.F.
