Perform window to viewport transformation for the point (20, 15). Assume that (X wmin Y wmin) is (0, 0) ; (Xwmax, Ywmax ) is (100, 100) ; (Xymin, Yvmin) is (5, 5) > (Xvmax. Yumax) iS (20, 20). The value of x and y in the viewport is

• A. x = 4, y = 4
• B. x = 3, y = 3
• C. x = 8, y = 7.25
• D. x = 3, y = 4
