Which one of the following statements is NOT TRUE? O a. If H is a p-dimensional subspace of Rn, then a linearly independent set of p vectors in H is a basis for H. O b. The dimension of Nul A is the number of variables in the equation Ax = 0. O c. If B = {V1,..., V p) is a basis for a subspace H and if x = C₁V₁ +...+ Cpvp. then C1₁,..., Cp are the coordinates of x relative to the basis B. O d. The null space of an m x n matrix is a subspace of Rn.
