In the diagram, ABCDABCD is a trapezoid with ABAB parallel to CDCD and with AB=2AB = 2 and CD=5CD = 5. Also, AXAX is parallel to BCBC and BYBY is parallel to ADAD. If AXAX and BYBY intersect at ZZ, and ACAC and BYBY intersect at WW, the ratio of the area of △AZW\triangle AZW to the area of trapezoid ABCDABCD is

(A) 7:1057 : 105 (B) 8:1058 : 105 (C) 9:1059 : 105 (D) 10:10510 : 105 (E) 12:10512 : 105
