Q. 40 Let m> 1 and n > 1 be integers. Let A be an m x n matrix such that for some m x l matrix b1, the equation Ar = b1 has infinitely many solutions. Let b2 denote an m x1 matrix different from b1. Then A = ba has (B) a unique solution for some b2. (D) finitely many solutions for some ba. (A) infinitely many solutions for some b2. (C) no solution for some b.
