Let M CR be the subset defined as M = {(r, y, z, w) | a? + y = 1, z w = 1}, %3D and consider the point p (1,0, 1,0) E M. Which of the following statements is true? O M is a 2-dimensional manifold and TyM = {(0, a, 0, B) | a, BER}. O M is a 2-dimensional manifold and TyM = {(a, 0, B, 0) | a, E R}. O M is a 3-dimensional manifold and TpM = {(0, a, B, )| a, B,Y E R}. %3D O M is not a manifold of any dimension.
