Check the true statements below: OA. det AT = (-1)detA. OB. If A is 3x3, with columns a1, a2, a3, then det A equals the volume of the parallelpiped determined by the vectors a1, a2, a3. OC. If one multiple of one row of A is added to another row, the eigenvalues do not change. D. If (A – r)k is a root of the characteristic polynomial of A, then r is an eigenvalue of A with algebraic multiplicity k. %3D
