Let m>1 and n > 1 be integers. Let A be an m *n matrix such that tor some m* 1 matrx b, the equation Ax = b, has infinitely many solutions. Let b, denote an m * 1 matrix different from b,. Then Ax = b, has (A) infinitely many solutions for some b ()no solution for some b (B) a unique solution for some b (D)finitely many solutions for some b
