Let A be a 5 x8 matrix and let rref(A) denote its reduced row echelon form. Which of the following is the following statements is always TRUEZ If the number of pivots of rref(A) equals five, then the columns space of A is R°. If rref(A) has five pivots, then the columns of A are linearly independent. If the columns 2, 3, 4, 5, and 8 of rref(A) are exactly the ones that have no pivot, then the nullity of A is 3 None of the suggested statements is is true. If columns 2, 3, and 8 of rref(A) have no pivot, then A must have 2 linearly independent rows.
