In a triangle XYZ, XZ is the longest side, length of which is 1 unit more than YZ, which again has length 1 unit more than XY. If area of the triangle is 10 and the shortest side is 3. What are the lengths of the three sides?  Select.
A) 1, 2, 5	B) 3, 4, 5	C) 4, 5, 6	D) 7, 8, 9	E) 5, 2, 4
XY=3   YZ=1+XY = 4   XZ=1+YZ=5   3, 4, 5 is the correct option.
