Mark only TRUE statements. O a. If the augmented matrix of a system row reduces to a matrix having a row of zeros, then this system is consistent. O b. The Gaussian elimination and Gauss-Jordan methods can produce extraneous, or extra, "solutions" that are not actually solutions to the original system. Oc. Every square reduced row echelon form matrix is upper triangular. Od. It is possible for the homogeneous linear system Ax = 0 to have a nontrivial solution and the related linear system Oe. If A and B are n x n matrices such that AB is nonsingular, then A is nonsingular.
