Let the linear map f:R³ → R² and h: R² R³ M (f) be the matrix associated with f and " M (h) be the matrix associated with h relative to the standard bases respectively. Then which of the following is true? A. M(h) is a 4x2 matrix, M (f) is a 2x3 matrix and M(hof) is a 4×3 matrix. B. M (foh) is a 4×3 matrix, M (f) is a 2x3 matrix and M(h) 4x2 matrix. C. Both M (f) and M(h) are invertible since the linear maps f and h have inverses. D. M (f) is a 3×2 matrix and M(h) is 2x 4 matrix
