Let ABCD be a tetrahedron, where A= (2,0,0), B = (0,4,0). If edge CD lies on line x -1/1 = y - 2/2 = z - 3/3 , such that centriod (α,β,γ) of tetrahedron satisfies 2α - 5/2/1 = β - y1/a = y - z1/b then which of the following are CORRECT?
(A) a + b = 5/2
(B) y1 + z1 = 19/4
(C) y1 - z = 1/4
(D) a + b + y1 = 5
